Your bite is from a rove beetle, Staphylinidae. Most rove beetles look like earwigs without the pincers, but not all.
Rove beetles are a family of garden predators. Also known as trash beetles, these beneficial insects are often found in leaf litter, mulch, under loose bark, and around fallen trees. They may also be found in bird nests and rodent burrows where they presumably feed on fly and flea larvae.
Adult rove beetles eat an astounding number of insect pests, as well as root maggot eggs and larvae.
Many rove beetle species produce secretions. Some of those secretions are toxic and can cause skin irritations, though serious problems are rare. As always, if you feel an allergic reaction coming on, seek medical assistance right away.
