This large insect was found in my alfalfa mix hay- the 2nd one I have found. It resembles a blister beetle variety I've seen and I wanted to confirm. Although this one is missing the antennae, the other one I found was live and had them- but I did not take a picture. It was identical to this one though in size and markings. They are almost an inch long and my young 3yo mare has been pretty consistently experiencing diarrhea and swollen hind legs and my gelding had been acting more lethargic and experiencing more metabolic issues than previous. This hay would be from Lindstrom (Chisago county).
