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.

Chelostoma rapunculi. Invader from Europe. Mostly occurring in the Canada/U.S. border and loves introduced bellworts. We have other pictures of this species, but here is an undercarriage view of the abdomen with all the male options in view. Those crazy insects have come up with a completely different mating system and creates lots of complexity in the males.

Am playing around with a 10X rig at home right now and aiming at some common species. Here is a seed pod of lamb's quarters. The round objects may or may not be what they call glandular hairs. This is unclear to me.
