Life Cycle
Adults are active on bark of damaged or fire-killed pines, including Loblolly Pine, Pinus taeda. They run so quickly they may be mistaken for crickets. Come to lights. Eggs are laid in bark and larvae feed on sapwood, then tunnel deeper, often tunneling within a single annual ring. Pupation is inside the tree and the newly-emerged adults chew their way out. Life cycle is one year in North Carolina Piedmont.
occasionally found w/ pseudoscorpions on hind legs:
