Hairy Beetles Pollinating Apple Flowers - publicphoto.org/plants/hairy-beetles-pollinating-apple-fl...
I love bees. And I always wanted to capture them in a picture. I really like this shot. I like the colors and the propotions. I think in some way this picture looks really professional and positive.

Cross pollination in Primrose (Primula vulgaris) - the series shows both ‘pin eyed’ and 'thrum eyed' forms of the flower and illustrate the mechanism that ensures cross pollination.
Primula vulgaris (Primrose) has two forms of flower, a situation known as heteromorphy. In the two forms, the styles are of different lengths. If the style reaches to the top of the flower tube, it is the 'pin eyed' form, and the anthers are halfway down the tube. In the other form (known as 'thrum eyed'), the style is halfway down the tube and the anthers reach to the top. Heteromorphy is one example of a mechanism that encourages self-pollination.
When an insect inserts its proboscis into the flower, pollen is deposited in the right place for the style of the other form of the flower - so pollen from a pin eyed flower reaches the stigma of a thrum eyed flower, and vice versa. The stigma of a thrum eyed flower has short papillae whereas the stigma of a pin eyed flower has long papillae.
Pollen grains from a pin eyed flower are small and more likely to stick to the short papillae on the stigma of a thrum eyed flower (than to the longer papillae of a pin eyed flower). The converse occurs with the large pollen grains from a thrum eyed flower.
Even if self-pollination does occur, it rarely leads to fertilisation so that heteromorphy in these plants appears to be associated with self-incompatibility.

The flower is approximately 30 mm across and 30 mm tall.

Pollinator of Platanthera chlorantha; the orchid pollinia are sticked to the eyes of this Noctuid moth.
Focus stack of 80 shots using a reversed Nikkor 24mm at f/5.6 on a 20mm macro ring connected to a Nikon D3s, diffused light with a Nikon SB-800.
I used a Cognisys StackShot and Helicon Focus.
This photo was taken along the exterior fence of the Marie Selby Botanincal Garden in Sarasota Florida, USA. The picture is unaltered with the excetion of cropping.
Pollinator Planets. Two hanging baskets tied together. Filled with Bits of Ben's fur, twigs, hose pipe, ivy, old bark, fluff from the tumble drier, small branches and moss. I am really pleased with it.
Bees are found on every continent except Antarctica, and they have an important role in pollination and producing honey and beeswax. Photos: Jon Sullivan and Jack Dykinga

Goldenrod is pollinated by insects, not by breezes in the air which make your allergies flare; inconspicuous ragweed pollen in the air is your actual culprit.

This is a picture of the Common Eastern Bumblebee, Bombus impatiens, pollinating the flowers of an azalea bush. This is of the azalea bush in my front yard in Jacksonville, North Carolina. Bees are one of the world’s major pollinators. While other animals help with pollination, bees are much more proficient at it than any other animal. With their large body size and the vibrations caused by their wings, they can shake pollen loose from the flowers. Their furry bodies then pick up the pollen and deposit it on pistols of the next flower visited. Normally, these bushes are full of bumblebees, but due to the extremely cold temperatures this year there were very few to be found. This one was very busy and I had to chase it around for a while in order to get this picture.
