Examples

“Housed plants are considerably injured by an oval bark-louse, the Coccus Hesperidum of Linnæus, which has been introduced from abroad.”

“Another group of insects that tend⟳ to be very secretive in their habits and were very well represented in the ancient forest are the bark lice, or psocids.⁶⁸ Bark lice (90) are usually solitary, but sometimes the adults and nymphs live⟳ together under webs spun out of silk emitted from head glands. They are found not only in litter but, as their name⟳ implies, on and under bark.”

“These include⟳ springtails (order⟳ Collembola), bark lice (order⟳ Ps[o]coptera),[…].”

“When present⟳ the wings are membranous, with reduced venation, with the hind wing coupled to the larger fore wing in flight and at rest⟳, when the wings are held roof-like over the abdomen (as shown here for the bark louse Amphigerontia contaminata (Psocidae); after Badonnel 1951).”
