Acantholyda erythrocephala (Linnaeus, 1758)
pine false webworm
The larvae live more or less gregariously on about one year old branches. The eggs are deposited in rows of 3-12 on the upper side of the needles, glued to each other. There is a communal web, but within it every larvae has its own small web covered with a few faecal pellets. About ten year old trees are favoured. Pupation in the soil, not in a cocoon.
