For sure, this is a Heteroptera (a suborder of Hemiptera), and it is likely predaceous (posture, eye size, beak shape). What I can make of the wing pattern suggests a Miridae (a very large family of mostly plant feeders). The head makes me think Reduviidae (assassin bug), but the beak, although I have not seen a clear view of its entirety, seems 4 segmented, not 3-segmented, and other characters don't match. Nabidae (Damsel Bugs) also comes to mind, which are also predaceous, but the wing pattern does not seem to match and they tend to be smaller, although I don't know the actual size of your subject. Sorry for not being more helpful.

"I doubt this insect is the one the folks from the Smithsonian Institution were looking for; Google searches associating the plant name with candidate families or even the suborder (heteroptera) did not turn up anything of interest. Also, I would expect the close associate to be a plant feeder, not a predator using the plant merely as a stand. But again all these are guesses and I may be wrong."

I had asked him if he could help with the ID.
