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.

Mystery Wasp....I think it is a Chalcid, but a couple of people have now suggested that is likely a Leucospis. This was from 2014 and was collected in Anne Arundel County and... I can't quite recall why we took this picture. Can someone id the wasp for us?Thanks Pilgrims. Picture taken by Wayne Boo.

A series of pictures of a male and female species that loves Bellflowers (Campanula). Meaning that the female of this species provisions its nest (note: males never help in all Hymenoptera) with the pollen of this plant.

Chilimalopsis parvula - according to Laurence Packer (world's expert on the bees of Chile) this is a range extension of this species, mapped specimens seem to indicate that it mostly have been captured well to the north of Santiago and we spent all our time to the South on the expedition. Anders Croft took the pictures.

A lovely dark Centris with blue highlights and a cape of white. Eyes like coals. What is it thinking?
