usually it's a type of bite that either a bug (such as a horse fly and so on) or an insect did (such as a spider, tick, flea, BED BUG! and so on)
A tick bite is a bug bite. Tick bites hurt a lot. Other bites tend to itch. I found my tick & bite because it itched a lot. It is a tick bite if there is a tick on it although baby ticks can be as small as a piece of pepper. ICK!
It can be a tick: round with short legs or lice, they both have 6 legs.
There are many types of black teardrop shaped bugs. It could be a type a beetle, flea, or even a tick.

If you are referring to the snow flea, then the diet of the snow flea consists mainly of the mold and fungus found on decaying leaf matter.
