< back | next >

Food Plant: Euonymus europaeus (Spindle), E.japonicus (Japanese Spindle)

Egg: laid in batches of 25-50 ova

Mine: May-June

Notes: The larvae usually overwinter beneath the protective egg covering. and communally mine a terminal shoot, which then droops (Emmet, 1996). The larvae make small full depth blotches initially (Robbins, 1989). The larvae then fed gregariously on the leaves in a web. The black heads of the larvae enable distinction between Y.plumbella on this host as Y.plumbella larvae have pale brown heads. White cocoons are formed in a web, usually near the bottom. Commonly found.
