Range
Throughout North America.
Food
Predatory on other insects.
Life Cycle
Incomplete metamorphosis: eggs hatch into tiny nymphs which molt several times as they grow to adulthood.
Remarks
Many species can inflict a painful bite on humans if handled, so it's wise to avoid touching them. If one lands or is seen on your body, brush it or flick it off with a sideways motion. Do not slap or swat it because it will almost certainly bite if you try to crush it.
