I awoke one morning to find that I was bitten near the base of my thumb and my pinkie. It looked very red and unlike the usual mosquito bites. It didn't really itch too. Two days later, local swelling near the bite marks occured, and my plam was almost twice its usual size and I was throbbing in pain for two days. When the swell subsided, the itching came. I've never been bitten like this before so I am curious to know what bit me. A friend of mine shared the same sypmtoms, and told me the insect is oval in shape, looks flat with no feelers, whitish/greyish in color, and about 5 to 6mm in length. I saw this insect on the floor that day and killed it. Just can't trace on the net what it was and if it was really this insect that bit me, which would be amazing, and indeed scary.
We've always called those insect "Silverfish". I'm not sure if it's technically correct, but I do not think that they bite. Certainly, it seems that whatever bit you had some venom...if you hand swelled so much. Possibly a spider...but these things pass, don't they?
