After my sister sent that link, I decided to search "deer fly" rather than "black fly." It works better, resulting in the following links: from Ohio State University, from yahoo, and finally, this one. There are more, but most of these searches are already overlapping.
In thinking about it, we have never had many classic Adirondack black flies in Samsonville. They are deer flies, as described in the OSU link. That must be what bit me.
Also, I've added a "Lyme Disease" tag to these posts.
A few weeks ago I added another record in the Brown Recluse Spider bite site. I had to create a new one, rather than just adding the incident to the existing record from the 1984 bite. I decided to share it there not because it is due to a BRS this time, but just because that is a great site that people go to for information when they have a weird reaction or rash.
I have to go back to the doctor for a follow up. He asked me when I was there on the 14th whether I consider myself to be at high risk for Lyme Disease. Am I outdoorsy? I said yes, definitely. Not that I am one for camping or tromping through weeds, because I am not. But I am not exactly a couch potato and my surroundings are often rural. I am careful about checking for ticks (I've never found one attached) and wearing long pants etc. in risky areas. But both Samsonville and Castleton are known as places for deer and ticks and I always hear that so-and-so has Lyme Disease. Rudy had Lyme Disease when he was about 7, at that time we used to walk him at Schodack Island State Park (we stopped as soon as we figured out that it is loaded with ticks near the Hudson).
When he asked me, I didn't say yes for this reason, but Castleton has tons of mosquitos (although I think they may have been worse in some past years), and Samsonville is loaded with deer flies (especially this year).
