Food Plant: Aster tripolium (Sea Aster)

Egg: Underside of leaf

Mine: Octoberl - May; July - August

When it leaves this mine it may window feed but often it makes full depth shorter mines (similar to those of Scrobipalpa salicorniae).It may also mine stems. The larva overwinters. The larva forming a coccon is shown
