Tiny Ceratina from Panama...in the first picture in this series you will see a rod going into its body to hold it in position for photographing in our mini bee studio. Actually this is not a rod but the very tip of the finest acupuncture pin. Yep, that is a small bee.

Yep, there are a lot of Ceratinas out there in the world. Here is the last in the series of Ceratinas from Sandra Rehan. As usual it is a small one from Panama. Tiny bees almost always have plenty of wing pop...no exception here.

A male Ceratina species from Bee Gardens in San Francisco that are surveyed for bees by Jaime Palawek. This crisp litte bee is less than the size of a grain of rice (white, long grain) and glitters with smooth metallic blueish green colors. Glinty enough to be problematic when photographing.

Playing a little bit here with a dark gray rather than black background, thoughts welcome. Yet more Ceratina pictures, diversity demands it. This series is from specimens collected in Panama by Sandra Rehan (UNH) as part of her mission to know everything there is to know about Ceratinas.

More Hylaeus from Panama, this little species was collected by Sandra Rehan, lovely wing pop or wing interference patterns. So glossy you can see the camera lens in the reflections.

This lovely purple blue Chrysidid wasp was found be Gene Scarpulla on the dredge spoil augmented Hart-Miller Island in the Chesapeake Bay. It is interesting to ponder whey these nest parasites are inevitably a bright metallic color and not something seemingly more cryptic (cryptic to an insect and cryptic to a mammal are likely two different things).

Ah....the redbud a lovely native leguminous north american small tree. Widely planted, awesome pollinator pollen and nectar food source...and...very interestingly, it has clear seed pods until mid summer which allows investigators to look at rates of pollination....could be used as a sentinel and a great citizen science project.
