Ceratochrysis declinus Bohart, U, Back, MD, Baltimore County

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).

Cercis canadensis, 2, Redbud, Howard County, Md,

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.

Cetntris attripes, face, m, Fayette Co, TX

A nice fluffy male Centris attripes from Central Texas collected during a family reunion. Centris are large bumble bee sized bees and as you move into desert and tropical area in the Americas the number of bumble bees decline and the number of often oil using Centris species and the equally large Carpenter bees increase.

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.

The very small and skinny, beetle hole nesting, Chelostoma philadelphi. A specialist on Philadelphus (mock orange). This species is most commonly seen on the non native European Mock Orange that was widely planted in the olden days.
