think this is a brown membrane bee/hylaeus heraldicus (of the family colletidae), a vey small bee (3-13mm)…
On Arum Lily taken wit ext tubes and Raynox DCR-250 giving a 1:4 magnification, so this head is about 2mm wide. It sat there so quiet I had all the time to set up things and approach it within 10cm...
The nictitating membrane (from Latin nictare, to blink) is a transparent or translucent third eyelid present in some animals that can be drawn across the eye from the medial canthus for protection and to moisten it while maintaining vision. Some reptiles, birds, and sharks have full nictitating membranes; in many mammals, a small, vestigial portion of the membrane remains in the corner of the eye. Some mammals, such as cats, camels, polar bears, seals and aardvarks, have full nictitating membranes. Often called a third eyelid or haw, it may be referred to in scientific terminology as the plica semilunaris, membrana nictitans, or palpebra tertia.

Ospreys also have a third eyelid called a 'nictitating membrane'. This is a transparent membrane that sweeps horizontally across the eye like a windscreen wiper and helps the eyes remain clean and moist.

"Drie van de zes oppervlakten van de kubus zijn gemaakt van flexibel membraan (spiegelfolie) met daaraan een luchttank verbonden. De andere drie spiegels bestaan uit semi-transparant spionage glas. Door het opblazen en leeglopen van de luchttank wordt het membraan hol of bol waardoor de weerspiegelingen veranderen. De heldere weerspiegelingen van het glas, de doorschijnende spiegels en de ruige verschijning van het schroevendraaier-mechanisme van de balg, sluiten elke vorm van digitale illusie uit en stellen ons gerust dat de deformatie en de desintegratie echt is."
Some folks don't like bird pics that sport nictitating membranes over one or more eye, but I like to share such shots for that very reason...because many folks just throw them away due to the lack of a crystal clear eyeball in the pic.
So, if you like birds that occasionally sport nictitating membranes, you've come to the right spot on flickr :).
Sandhill cranes, have a special transparent third eyelid called the nictitating membrane that sweeps horizontally across the eye to clean, moisten, and protect it from dust, debris, and predators while allowing them to maintain vision, acting like built-in goggles.
Excerpt from scotiabankcontactphoto.com/2022/core/vid-ingelevics-ryan-...:
Since 2019, Toronto-based artists Vid Ingelevics and Ryan Walker have charted the progression of the Port Lands Flood Protection Project, one of the most ambitious civil works projects in North America. This third series of photographs, presented on wooden structures along the Villiers Street median, focuses on the extraordinary operation of building a new mouth for the Don River and the careful methodology employed in the naturalization of a massive industrial brownfield.
The first photographic series that Ingelevics and Walker produced about this site, titled Framework (2020), captured the buildings and structures demolished to make way for the river excavation. This demolition allowed for the massive movement of soil captured in the second series, A Mobile Landscape (2021). How to Build a River documents how this soil removal made way for the river to be constructed using bio-engineering practices. It reveals the innovative bioengineering techniques used to construct this complex ecology and its multiple engineering layers, which will soon be invisible—either submerged underwater or beneath park surfaces—when the project is finished.
As the excavation has proceeded and workers have brought materials to the site and carefully categorized, prepared, and positioned them, Ingelevics and Walker have witnessed the river’s path quickly taking shape. The images in this series follow the rigorous steps taken to protect the new riverbed and future ecosystem, with multiple layers of sand, charcoal, and impermeable geosynthetic clay liner added to block contaminants caused by almost a century of housing fuel storage tanks in the Port Lands. The photographs capture the ways in which the new riverbanks (known as “crib walls”) were stabilized with logs, tree trunks, rocks, and coconut fibre material, and track the meticulous creation of future habitats for fish and birds.
Fish Habitat (2019) shows the development of a new riparian habitat, which includes coloured streamers strung across the water to deter geese from landing and eating vegetation that will provide food for fish. In Stratified River Ingredients (2021) a worker strides past stepped blankets of biodegradable coconut fabric, which will help hold the riverbank soil together until plant root systems are in place. In this series the new river comes to life. Its plants and banks, its roots and rocks and sands can all be seen coming together in Meander (2021). All of these innovative bioengineering techniques have been employed in similar projects around the world where nature is fast-tracked, but it’s unusual to have so many techniques applied simultaneously, and on such a vast scale.
At times during this massive project, something as small as an unidentified plant can halt construction. Transplanting #1 and #2 (2021) show crews salvaging plants for storage after strange, bulrush-like plants sprouted unexpectedly after 100 years of dormancy underground. These were likely remnants of the site’s original wetlands, which germinated when sunlight hit the excavated mud. Some of the plants were taken to a greenhouse laboratory at the University of Toronto, and others were transplanted to the Leslie Street Spit, located nearby along the waterfront. Even with the most meticulously planned naturalization processes, nature can still surprise us.
Following their documentation of the processes of destruction and removal required to prepare the site, this third series of work in Ingelevics and Walker’s multi-year project allows viewers to witness the construction of these new, interconnected habitats and structures. Their photographs offer glimpses into the makings of a highly creative built ecology, one that has looked to nature in order to artificially recreate it.

The nictitating membrane (from Latin nictare, to blink) is a transparent or translucent third eyelid present in some animals that can be drawn across the eye for protection and to moisten it while maintaining visibility. Some reptiles, birds, and sharks have full nictitating membranes; in many mammals, a small, vestigial portion of the membrane remains in the corner of the eye. Some mammals, such as camels, polar bears, seals and aardvarks, have full nictitating membranes. Often called a third eyelid or haw.

The protective eyelid came into play here for some reason....maybe a snowflake or reaction to a flying feather from the pigeon...

When I returned to this tree an hour later on my way back I found a couple of wasps looked different. Took shots then researched later. Turns out they have a very stretchable membrane between 2 abdominal segments that unfolds and makes a translucent bag when they are ready to deliver the egg. This strong membrane was what actually provided the force to pierce the wood during drilling. It contains a fluid that has lytic enzymes that digest wood. At the time, I had no idea what I was looking at but it was cool as heck.

The nictitating membrane is a “third eyelid” that extends from the inner corner of the eye to the outer corner. You may see it when a bird blinks.
Only Owls, Ostriches, and Parrots blink ! but all birds, mammals, amphibians, fish and reptiles have Nictitating membranes over their eyes but are rare in primates . Even humans had until we no longer needed them.
I discovered a fun way to do monotypes on YouTube that is fast and easy and cheap. You can see the how-to here:
Basically you ink up a plastic bag, place it over your paper, and rub the back of the bag to transfer ink to the paper. I rubbed with my finger, a cotton swab, and a sharpened wooden match stick to make marks and areas of tone. You can also scrape ink off the bag before you print to make white marks. You can lift the bag off the paper to see how things are going and put it back down again to continue.
These are the equivalent of a quick sketch. After you print one, you can use the ink that is left on the bag to print another. You get a negative.
These are all 5x7. I used water soluble block printing ink on watercolor paper. One advantage to this method is that you are not working in reverse. What you draw is what you get.
A membrane of sheer blue mesh protects the surrounding area from wayward construction byproducts. If only it could protect North Park from the gentrification it represents as well...
The nictitating membrane (from Latin nictare, to blink) is a transparent or translucent third eyelid present in some animals that can be drawn across the eye from the medial canthus to protect and moisten it while maintaining vision. Most Anura[1][a] (tailless amphibians), some reptiles, birds, and sharks, and some mammals (such as cats, beavers, polar bears, seals and aardvarks) have full nictitating membranes; in many other mammals, a small, vestigial portion of the nictitating membrane remains in the corner of the eye. It is often informally called a third eyelid or haw;
Little Wayne's nictating membrane. Red-eyed tree frogs cover their eyes with a semi-transparent lid called a nictitating membrane, which allows the tiny frog some limited vision during rest.
Zoom in and have a look at that eye!

Ok, I'm sort of a nut about taking making pics of birds that show them with one or both of their eyes covered by their inner eyelids, which are called nictitating membranes. You may not like them. I've heard other photographers say, "I throw all of that type of picture away." Well, I don't throw them away as long as the rest of the pic is in focus and is at least mildly interesting.

Dos importantes adaptaciones de los ojos de las aves son el pecten y la membrana nictitante. El pecten es una estructura en forma de peine, situada cerca de la base del ojo, que lo irriga y que también puede incrementar su capacidad para percibir imágenes poco claras. La membrana nictitante es el "tercer párpado", transparente, que limpia y protege el ojo y del que carecen la mayoría de los mamíferos. En las aves buceadoras desempeña el papel de lente de contacto, para corregir la refracción de la luz bajo el agua.
El ave parpadea desplazando lateralmente esta membrana sobre el ojo; como es transparente no pierde nunca la visión, excepto durante el sueño.
Two adaptations of the eyes of the birds are the pecten and the membrane nictitant. The pecten is a structure in comb form, located near the base of the eye that irrigates it and that it can also increase its capacity to perceive not very clear images. The membrane nictitant is the "third lid", transparent, that cleans and it protects the eye and of the one that you/they lack most of the mammals. In the birds divers it plays the part of contact lens, to correct the refraction of the light under the water.
The bird blinks displacing this membrane laterally on the eye; as it is transparent it never loses the vision, except during the dream.

I never knew that the red and yellow feathers on a male Red Winged Blackbird actually puff out. But here's evidence they do!
The Red-winged Blackbird is one of the most common birds in the US. Its most striking feature is the colorful patch on the male's wing which is called an "epaulet" by ornithologists, from the French word "epaulette" meaning a shoulder ornament on a military uniform. Sometimes the patch is concealed by black feathers so only a yellow fringe is visible.
During breeding season in spring and summer, the Red-winged Blackbird takes up position on top of a tall bush or cattail and spends most of its day defending its territory. However in fall and winter, Red-winged Blackbirds give up their aggressiveness and form "mixed foraging flocks" with other blackbirds. The female is different from the male in shape and color and is easily mistaken for a large sparrow.
