I don't know the scientific terminology... but, here's what happened to my neighbor. She was picking raspberries. She thought she got poked by a vine and thought nothing of it. She was wearing long pants - and the poke was on her shin. I believe it was the next day before the wound ulcerated - when I saw it, it looked like a huge hole and was swollen and red around it. It took a very long time to heal. This happened a few years ago. Last night she showed me the bite mark - it is still there and still bothers her. They did find 2 spiders, took them to the WSU lab and confirmed them to be hobo spiders.
Sounds like a "textbook" hobo bite. I've never seen one in person, but I've seen pictures of the progression. Their venom is just like the brown recluse. My degree is in Entomology (which is pretty darn useless for earning money), so I have a lot more experience with the textbook versions than the real ones, thankfully. I have a lot of spiders on my back porch that might be hobos (there are three species in the same genus, and all I can tell is they are too small to be the giant house spiders) so I've been working to clean up the debris around it.
I do not know what happened as I wasn't there, but my guess would be that the wound became infected and it spread? I'm a heck of a lot more scared of infection than I am of spiders.Thanks for the correction. Ok so its black widows who have the neuro toxin? I will remember that I just remember seeing a shoulder bite and they were talking amputation because so much had um... rotted away so to speak.
