Eastern Blood-Sucking Conenose Bug

Beetles, I think…
Hi!
All 61 pages of beetles on your amazing site have been viewed to no avail. Thought I had one of these beetles (they are beetles, right?) identified on BugGuide but, alas, no. The first, the long solid black one with the chunky hind legs, was moving very quickly on the front porch wall one day last summer. The other, the black and red one was quite a pest this last spring. I saw, felt, three of them inside my house which was built of rough-cut pine from the trees off the land here in the Great Smoky Mountains. By pest I mean that it lets you know it’s there by nipping, not tickling as most bugs seem to do, but leaves no mark. Each, in turn, was escorted outside, unceremoniously. Any ideas? I’d love to be able to name them properly.
Thank you,

Hi R.G.,
You couldn’t locate the Eastern Blood-Sucking Conenose Bug on our beetle pages since it is an Assassin Bug. The black and red pattern is quite distinctive. According to BugGuide, the Eastern Blood-Sucking Conenose Bug, Triatoma sanguisuga, is also called the Big Bed Bug or Mexican Bed Bug. It normally feeds on “Blood of mammals, especially Eastern Wood Rat, Neotoma floridana . Also feeds on bed bugs and other insects. Feeds at night.” Also regarding its habitat: “Natural habitat is nests of small mammals. Sometimes invades houses.” BugGuide also notes that it “Sometimes bites humans, and the bite may be severe, causing an allergic reaction ” but there is no mention of Chagas Disease which is spread by the related Western Conenose Bug. Chagas Disease is primarily a problem in tropical climates. We are still working on an identification for the other insect you sent in.
