What makes the long, leathery cocoons on our feijoa tree?
The common bag moth (Liothula
omnivora), a native partial to macrocarpa, manuka, kanuka, pines, wattles and willows as well as feijoas. The caterpillar within pokes its head out at night to munch on leaves, but bag moths don’t usually cause much damage: parasitic flies and wasps keep numbers down. NZ is home to more than 50 of the species, most unique to this country. Once hatched, the moths live for just hours; only the males have wings — females never leave their bag.
