was recorded on 2026-10-14 in Altoona, with 12 sightings in the past month across Cambria and Blair Counties.1 Adult females are now laying eggs through early freezing; each mass holds 30-50 eggs adapted to survive cold.1 Egg masses laid now will hatch next spring, so elimination of eggs before winter is the most effective control point in the pest's lifecycle.1
