Blood Sucking bug ID help needed! - Triatoma

Blood Sucking bug ID help needed! - Triatoma
Tonto Creek Wilderness, Gila County, Arizona, USA
July 3, 2006
Size: ~3/4 - 1 inch in length
Was out camping in a riparian area over the 4th of July holidays.

These bugs didn't seem to fly or have wings, they are definitely nocturnal (they made their appearance around dusk and seemed to be active all night), and definitely are blood suckers :(

I appreciate your assistance in identification as I know I was bitten numerous times and at least 2 were found engorged with blood inside my shelter!

Eric is right, Triatoma it is!
This is definitely a Triatoma. It doesn't have wings because it's a nymph. It looks about 4th-5th instar (and judging from the size you gave), so it's almost ready for its final molt into an adult.

Identifying to species is not easy with nymphs, especially since Arizona has many species.

oy ick. Well thank goodness I didn't have a severe allergic reaction (assuming we're not counting the numerous itchy welts I still bear).

Thanks for your help :) both Eric and Waspman!

Bloated Triatoma Nymph.
Oh, dear, you were bitten by a "bloodsucking conenose" in the genus Triatoma (assassin bug family Reduviidae). Fear not, our domestic species are not known to transmit Chagas' disease. Still, one tends to become 'more' sensitive to their bites over time. Surprised you did not have menacing, itchy welts where you were bitten. The saliva of these insects tends to aggravate one's immune system. I would definitely try to avoid becoming a victim a second time. Sleep enclosed in mosquito netting that is not in contact with your body. The normal hosts of these insects are wood rats. Perhaps a park crew removed the wood rat middens without eliminating the resident insects! Not a good idea.

are you sure? I looked at all
are you sure? I looked at all kinds of kissing bug/bloodsucking cone nose bugs, but they all seem to have wings on their backs...these ones, no matter how I look at the images don't seem to have wings...or is it because it was in "nymph phase" that it didn't have the traditional coloring on the sides or the wings...

As for the itchy welts, I didn't mention them because by thinking about them, I start itching again :( (needless to say, I'm still suffering)
