Entomology (Study of Bugs)/Little black bug that bit me


Found a very small, shiny, soft bodied black bug attached to my arm.  Pulled it off, put it on a napkin, and it crawled slowly.  Could not see legs, head or mouth parts from above.  It was about 3/10'ths of 1 mm. long and wide.  Squished it (wish I hadn't), and it was full of blood (MY blood).  It bit me twice, and the first bite is somewhat swollen, red and hard.  The second bite is just a bloody spot under the skin.  Does not itch.  Our cat likes to sleep in my chair.  Any ideas about what this mystery bug was?


I explicitly state in my profile instructions to questioners:  Please, no "what bit me?" questions.  Without at least an image of the creature in question, I cannot guarantee an accurate identification.

That said, it could have been a small (nymph) tick, a minute pirate bug, or even a black fly.  If it was literally attached to you, a tick is the most likely suspect.  Nymph (baby) ticks can be very small.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
