22-9-2017 MONTE CORONA, VALENCIA - GRASS EGGAR MOTH (Lasiocampa trifolii)
Lasiocampa trifolii, the grass eggar, is a moth of the family Lasiocampidae first described by Michael Denis and Ignaz Schiffermüller in 1775 and found in Europe.
Distribution and habitat of this moth is that it is found in Europe in coastal dunes.
Eggs are laid on leaves close to the ground, hatch in the autumn, and the young larvae hibernate. The larvae feed on grasses, various shrubs and deciduous trees, such as oak, European beech, poplar and Calluna. The cocoon is formed on the ground.
Adults' wingspan is 40–55 mm and it flies from June to September depending on the location (in Britain it is on the wing in August). They fly during the day, but also at night, and will come to a light. The female is larger than the male.
The Grass Eggar is reddish-brown in colour with a curved outer cross-line on the forewing and a central white spot. The colour varies with location. The pale form f. flava is a straw or brownish yellow with similar markings.
The adults are incapable of feeding. They fly at night and are attracted to light. The caterpillars can be found from March to July feeding at night. They pupate in a tough brown cocoon on the ground. They overwinter as eggs laid loosely among vegetation.
