The green objects are gametophytes of moss organisms, and the brown are the sporophytes, with the spore-bearing calyptras at the tops. The spores are usually released, and may be wind-blown to a new location. Moss sporophytes usually appear for a relatively short time. They grow out of the ovaries of the gametophytes, following fertilization. The green is long-lasting.
I am pleased to be the curator of a Gallery of photos of moss sporophytes, by other people. This Gallery has received over 3,000 views so far.
In the rose garden at the Ringling Museum. It was not the best day to photograph the roses because they had just been cut back and fertilized for the growing season, but I managed to find a few to capture.

When a pansy has finished blooming, the most interesting transformation takes place. A pansy can be fertilized by its own pollen or by the pollen bees transport to it from neighboring pansies. After pollination, the ovary behind the flower swells into a green seed pod, which remains on the stem after the petals fall. That pod eventually will dry and spring open to reveal three boat-like valves filled with small brown seeds about 1/16 of an inch long.
These two Red-Eyed treefrogs are in amplexus, a term for when the male of the species climbs on the back of the female and holds on until she starts laying eggs so he can fertilize them. The male may be on the females back for a couple of days before she finds a good place to lay eggs.
Normally eggs of these frogs are laid on the underside of leaves overhanging the water. As tadpoles develop in these eggs and start swimming around the eggs will all ultimately rupture and the liquid released from the eggs will help wash all the tadpoles into the water below where they can continue their development.
Note that males of this species are much smaller than females. This is helpful for the female who is often hanging upside down clinging to a leaf while laying her eggs with that male on her back.
I am going to start posting photos from my Costa Rica trip in 2017 again. I still have so many unposted photos from that trip to share and cold weather has me reminiscing about that wonderful trip. So I decided I will start with the beautiful Red-eyed treefrog.
Here are 3 images of different pairs of red-eyed tree-frogs seen in Costa Rica at night. They had either already mated or were preparing to.

The flowers with white spots are newer and have nectar. They are in need of pollination. The flowers with red spots indicate to bees and other pollinators to not bother to search for nectar in them. Those flowers are most likely pollinated and fertilized.
The mating of the tree white butterfly (Aporia crataegi) often takes place immediately after the females hatch. The males transfer sperm to the female, which is then used to fertilize the eggs when they are laid. The mated females can then lay eggs without further mating

Antennaria dioica (Asteraceae) 177 21
Antennaria dioica (mountain everlasting) is a Eurasian and North American species of flowering plants in the family Asteraceae. It is found in cool northern and mountainous regions of Europe and northern Asia (Russia, Mongolia, Japan, Kazakhstan, China) and also in North America (Alaska only).
Antennaria dioica is a herbaceous perennial plant growing to 10–20 cm tall, with a rosette of basal spoon-shaped leaves at their broadest near the apex; and smaller leaves arranged spirally up the flowering stems. The flowers are produced in capitula (flowerheads) with pale pink ray florets and darker pink disc florets.
It is dioecious, but can also reproduce without fertilization. It is found in groups which can be all-female colonies, all-male colonies, and also mixed colonies. The male plants have whiter flower heads than female plants. The species name, dioica, is derived from Greek as a reference to the separate male and female plants.

This is not a composite of multiple photos - it is a single photo. It is presented here just as it was captured by the camera, except that I made a slight crop and added a bit of focal soften in PicMonkey. The rainbow, the hill, and the guy (a stranger) all came together for me at the same moment.

Over fertilized plants may be beautiful but are otherwise useless, like people whose energies are devoted so completely to their appearance that there is no other development.

Extra Large organic lemon from my garden. It's really huge ! ( plz see my previous post for comparison with an egg ) I use organic chicken manure to fertilize them and they love water !
Sorry for posting so many photos, I'm kinda excited ! 😄
In this photo, a male and female dragonfly are seen connected after mating. The male remains attached to the female, a behavior called mate guarding. This ensures his sperm has the highest chance of fertilizing her eggs while they search for an ideal spot to lay them.
Giant water bugs are fierce predators themselves, sometimes consuming prey larger than themselves. They inject a digestive toxin into their prey and suck out the liquified remains. (Yuck!)
Interestingly, it is the male that carries the fertilized eggs on its back until they hatch.
When does a century plant bloom? A century plant will bloom once in its lifetime, usually between 25 and 30 years. Well-fertilized plants may bloom as soon as ten years, but most people avoid speeding up the blooming process, because the plant dies soon after blooming.
]Have a great day my Flickr Friends.
The New Mexican Whiptail Lizard like other whiptail lizards are all females who reproduce by parthenogenesis. Its eggs require no fertilization, and its offspring are exact and complete genetic duplicates of the mother. Since there is no genetic variation except that which occurs through mutation, the New Mexico Whiptail cannot evolve as other species do.
We have many of these that live in our yard enjoying whatever whiptail lizards enjoy doing. Another creature that likes to catch flies. This one is about to lay eggs and her babies will add to our whiptail population.

The green (what we usually expect if someone says, "look at that moss,") is the gametophyte phase of this moss. The plants make eggs, and sperm, that fertilizes the egg. Then, if all goes well, a non-green structure, the sporophyte, grows from the fertilized egg. Each sporophyte has a capsule on its end, and spores are grown there, then released, and washed or blown to another occasion.
This entire assembly was (and most likely still is) growing on a downed tree trunk.

Here is my attempt at a food picture. I wanted to something with eggs, since I have chickens and I LOVE the gift they give everyday! If you zoom in you will see spots on the yolk. This simply means that this particular egg was fertilized....my rooster is doing his job. It does not mean the egg would have hatched, since no girls are sitting on eggs.....so all is good! :-)

Peixe Lua_Moon Fish
Scientific Name: Mola mola (Linnaeus, 1758)
www.yesterdayslife.com/photofront/Helder697
O peixe-lua é o maior peixe ósseo do mundo, podendo atingir mais de 3 metros de comprimento e pesar mais de duas toneladas!
Esta criatura dócil deita-se frequentemente à superfície da água, deixando-se levar pela corrente. Este comportamento permite-lhe equilibrar a temperatura corporal após consecutivos mergulhos em águas profundas e mais frias.
Apesar da sua fisionomia bizarra o peixe-lua é um animal gracioso pela coloração prateada e pelo lento movimentar das suas duas enormes barbatanas.
As fêmeas produzem até 300 milhões de ovos de cada vez, que são libertados para a água e fecundados pelos machos. As larvas passam por três estágios de desenvolvimento em que o peixe perde a barbatana caudal e ganha uma série de espinhos conspícuos.
O peixe-lua destaca-se por transportar uma impressionante carga de parasitas. Até à data a comunidade científica identificou cerca de 50 espécies diferentes, entre parasitas internos e externos!
Devido à sua natureza delicada e aos movimentos lentos, estes peixes são facilmente capturados por redes à deriva e por outros métodos de pesca. Como consequência as populações poderão estar em declínio.
Sunfishes are the largest bony fish in the World, reaching more than 3 meters in length and weighing in at over 2 tons!
These docile creatures often lie on their sides on the surface of the water and drift in the current. This behaviour helps them adjust body temperatures after consecutive dives in deeper, colder water.
Despite their unusual appearance, sunfishes are graceful animals, with their silvery glow and slow mesmerizing movements of the two huge fins.
Females release up to 300 million of eggs in the water, which will later be fertilized by passing males. Developing larvae undergo three separate stages, some featuring numerous odd-looking spines and also the loss of a tail fin.
Sunfishes are notorious amongst the scientific community for carrying enormous parasite loads. More than 50 internal and external parasite species have been identified so far.
Because of their delicate nature and slow movements, sunfishes easily fall prey to drift nets and other fishing methods. Their numbers are suspected to be steadily declining as a result.
Tough to watch.. first, a rival male thing to muscle into the nest box and territory kills the first brood of five. The next brood is eaten by a raccoon just before fledging after he manages to rip off the defensive measures I created. the next brood does not hatch, possibly the eggs were not fertilized...she is sitting on brood 4 now and I am hoping the get at least a few offsprings.
We don't use ant chemicals. Not to get rid of bugs, weeds, or to fertilize. Nature is in charge, which is where I find most of my nature photos. Dragonflies eat everything they can, cutting down the mosquito population. Birds of all kinds nest and spend the season here. They too eat all they want. And then there's the trees. Magnificent trees, providers to all. I let them have the run of the yard spring to Autumn. When cold sets in, I trim everything back, getting ready for it all to happen again,
The rose bushes along our back fence line are bursting in flower this year. It boggles my mind as to why. I never fertilize them and we had a paucity of rain this year. This week there suddenly seems to be hundreds of them in all colors. They're definitely a double edged sword--beautiful in bloom and dangerous when I have to cut them back--such is the rose.

▶ "Stylophorum diphyllum —commonly called the celandine poppy or wood poppy— is an herbaceous plant in the poppy family (Papaveraceae). It is native to North America, where it is found in the eastern United States and Ontario. Its typical natural habitat is moist forests.
In spring, the deep yellow flowers of the celandine poppy appear as a brilliant display on the forest floor. The flowers have 4 yellow petals, two soon-falling sepals, many yellow-orange stamens, and a single knobby stigma. They appear singly or in umbels of two to four flowers from early spring to early summer. After fertilization, a bristly blue-green pod hangs below the leaves [as seen above]."

Under the blue-green
Isinglass of the sea
I hear the melody
black Jewelfish sing
as sleek males hum
their love songs
the sonic muscle
a mating organ Bach
might have played
in the 17th Century if he
had lived in the Pacific reefs
off Santa Catalina, which,
on a clear day Bill Ackerman
in his youth could see
from Laguna, but the males
have no interest except
in the bubble nests where
fertilized eggs will pulse
in the currents, a kind
of rhythmic tempo Johann
Sebastian might gather
in his arms as rainbow-hued
Paradise Fish and Barbs
and Blue Bettas and Deltas
swim through his fingers
on the way to spawn,
a small cantata starting
or a concerto which
by the end of the day
as westerly trade winds
sweep in will swell to a
choral masterpiece even
the sun might notice as it
crescendos gloriously into
the flaming horizon
--Miguel de O
Arboriculture is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants. The science of arboriculture studies how these plants grow and respond to cultural practices and to their environment. The practice of arboriculture includes cultural techniques such as selection, planting, training, fertilization, pest and pathogen control, pruning, shaping, and removal.
Hope, this tree survives....

Still Attached: It’s Not You, It’s Evolution
Here we see two dragonflies in a relationship that can best be described as “committed with boundary issues.” The male is literally hanging on to the female while she lays eggs, which in bug terms is known as mate guarding and in human terms would get you a restraining order.
Why does he do this? Because he wants to make sure it’s his DNA going into those eggs. He’s not taking any chances with a rival swooping in at the last minute and pulling a Maury Povich. So he latches on, midair, mid-pond, like a tiny green helicopter couple in marriage counseling.
Is it romantic? Not exactly. But in the dragonfly world, it’s effective. And let’s face it—when you’ve only got a few weeks to live, you don’t waste time on long walks on the beach. You cling. You fertilize. You move on.
For a creature with a brain smaller than a sprinkle, that’s pretty impressive planning.
Couplet:
He grips like Velcro, won’t let her flee—
'Cause love’s just biology with a warranty
Usually the water lilies bloom more in the early summer after they get fertilized during the spring clean out. This one must have decided it wanted some late summer joy and also stood proud of the water surface, also unusual. Large view will show a fly on one petal.
Picardie is one of the 26 regions of France, and is located in the northern part of France.
Picardy (French: Picardie) is a historic region in northern France that is now within the departments of Aisne, Oise, Pas-de-Calais, and Somme. Amiens was the region's capital.
On Picardy's fertile soils they grow wheat, sugar beets and fodder crops. Dairy and beef cattle are raised, and intensive vegetable cultivation takes place on the heavily fertilized, drained peat in the valley of the Somme River.
Between the 1990 and 1999 French censuses, the population of Oise increased at the brisk pace of 0.61% per year (almost twice as fast at that of France as a whole), while the Aisne department lost inhabitants, and the Somme barely grew, at a laggard 0.16% per year. Today, 41.3% of the population of Picardie live inside the Oise département, which historically was not part of Picardy.
From an area 30kms North of Paris, close to Roissy Charles de Gaulle airport, the Southern boundaries of Picardie stretch eastwards towards Champagne and the Belgian border. Westwards, the region extends to the English Channel.
This ancient region will not disappoint visitors. With its 4,000 hectares of lakeland, 1,200kms of rivers, 70kms of sand dunes, mighty cliffs and brilliant beaches to coastal marshes, forests and bays at the river mouths of the Somme and the Authie, there is always something for everyone to be amazed at.
Butterflies reproduce the way other animals do -- sperm from a male fertilizes eggs from a female. Males and females of the same species recognize one another by the size, color, shape and vein structure of the wings, all of which are species specific. Butterflies also recognize each other through pheromones or scents. During mating, males use clasping organs on their abdomens to grasp females.
Many male butterflies deliver more than just sperm to their mates. Most provide a spermatophore, a package of sperm and nutrients the female needs to produce and lay eggs. Some males collect specific nutrients to produce a better spermatophore in an attempt to attract a mate. Some females, however, don't have a choice -- in some species, males mate with females before they have left their chrysalis or swarm the chrysalis waiting for the female to appear. In most species, males and females look a lot a like, but females often have larger abdomens for carrying their eggs.
Females store the sperm in a sac called a bursa until she's ready to lay her eggs. She fertilizes her eggs as she lays them, using the last sperm she received first. For this reason, males of some species will leave a substance that dries into a film on the female's abdomen in an effort to keep her from mating with other males. Females lay their eggs one at a time or in batches of hundreds depending on their species.
A butterfly has to take special care when laying eggs. The eggs must be kept warm and at the right humidity level. Too much moisture and the egg will rot or be attacked by fungus. Too little and the egg will dry out. Caterpillars also need to start eating as soon as they hatch, so most of the time females place the eggs directly onto a plant the caterpillar will eat. Typically, the eggs attach to the underside of a leaf so they are hidden from predators.
In spite of all the effort female butterflies make to protect their eggs, very few make it to adulthood. Ants, birds and other animals can eat the eggs themselves. Also caterpillars and butterflies are popular snacks for everything from birds to bats. Some insects also lurk in or around flowers to prey on adult butterflies. A butterfly's chrysalis also has few defenses from predators and, at all stages of life, a butterfly can succumb to fungi and diseases.
Parides iphidamas is a species of butterfly in the family Papilionidae. It is commonly known as the Iphidamas Cattleheart and the Transandean Cattleheart.
Between the streams near the village of Chaam in the south of the Netherlands, is a small nature reserve: 't Reservaatje.
It lies on the Low Heiveltse brook and consists of pasture with many flowers, two ponds and a wooded bank.
There graze cows in spring and summer. In this way, the grass is kept short in a natural way, fertilized and amount, and other plants have the opportunity to grow, which in turn attracts animals.
☛ This is what we saw during our Bicycle tours in the Netherlands, where we have cycled through the beautiful landscape.

I have 10 African Violet plants, many have multiple plants growing in one pot... they are all in bloom!!
Very easy plant to grow... some of mine are over 30+ years old... they are in clay pots sitting in a bowl or tray... I water from the bottom once a week and never fertilize!!
It is a treat for me to find these monstrous moths, though I read that they aren't rare. This fellow was hanging on to a twig, waiting for darkness. Lacking a digestive tract, they don't feed, but the males follow a pheromone trail to the female, sometimes miles away, where they set about creating the next generation. She lays the fertilized eggs and they both die soon. For a few nights in June, I see them flitting about in the car headlights, then they are gone for another year.
Cattleya lawrenceana is a species of orchid in the genus Cattleya. It is native to Venezuela, Guyana, and Brazil, where it grows at elevations of 250 to 2,400 meters . It is a relatively rare orchid species.
This orchid is an epiphyte, meaning it grows on other plants for support. It has pseudobulbs that are about 20 centimeters tall and carry a single, oblong-lanceolate leaf that is 20 centimeters long. The flowers of Cattleya lawrenceana are large and showy, with three to five flowers per inflorescence. The flowers are typically lavender or rose-colored, with a darker lip.
Cattleya lawrenceana is a relatively easy orchid to grow, and it is a good choice for beginner orchid growers. It prefers warm to hot temperatures, with moderate to high humidity. It should be watered regularly, but allowed to dry out slightly between waterings. Cattleya lawrenceana can be fertilized monthly during the growing season with a balanced orchid fertilizer.
Autumn and orchids will arrive on March 20th in Brazil.
This damselfly was waiting for. her mate. See the next couple of pictures. She has already received his sperm and is looking to deposit those fertilized eggs on the plant below the waterline.
