I was mowing my under a pecan tree when I felt an intense sting in my back and when I got up I found the black bug dead and the one that looks like a wheel bug in the seat, I was really hoping that you could id both bugs for me and let me know if I need to worry about anything like chaggas disease, sorry to come off like a hypochondriac but it just worries me a little is it a wheel big or a kissing bug they both look similar thanks
This looks like a wheel bug, not one of the reduviids that transmit Chagas disease. Those bugs usually bite at night and the bite is painless. I can't see enough detail in the second image but it was probably a large fly that the wheel bug had captured.
I can answer questions in any area of entomology (study of insects, spiders, mites, ticks, and other terrestrial arthropods). Contact me about home and garden insects, insects that bite and sting, and insects that damage homes such as carpenter ants and termites.
