wasp

A minute, pale to reddish mite that lives among feathers and nesting material of wild and domestic birds, sometimes dispersing into nearby buildings when nests are abandoned.
arachnid

A tiny, black-and-white patterned true bug barely visible without close inspection, the minute pirate bug is a voracious predator of thrips, mites, and insect eggs on flowers and foliage.
true-bug
