Your letter to the bugman:  We were in a local pumpkin patch when my daughter turned a pumpkin over and found this bug scurrying away. We found several others during our time there. They were about 1/2 – 3/4 inch long. A bug app I use identified it as possibly a blood-sucking conenose or a Spartocera fusca. I would love your thoughts!
How you want your letter signed:  Rose

Immature Western Corsair Bug OR

Dear Rose,
While this is an Assassin Bug, it is not a Blood Sucking Conenose Bug, AKA Kissing Bug, which spreads Chagas Disease.  Your individual is an immature Western Corsair Bug,
Rasahus thoracicus, which we verified on BugGuide.  According to BugGuide, some females are wingless:  “Some brachypterous females in the guide may have been listed as immatures. It is hard to tell the difference. Nymph’s wing pads have a broader base. ‘Microwings’ of adult females are hinged, like full-sized wings.”  While they are not considered dangerous, Corsair Bugs might deliver a painful bite if carelessly handled.
