Bedellia somnulentella

The larvae of the moth Bedellia somnulentella feed on Bindweed and related species, initially in an inconspicuous narrow and very contorted gallery.  The egg is oval, not round as with Stigmella species. Later instars leave the gallery and feed in a transparent blotch mine. The rear end of the larva sticks out of the undersurface of the leaf, and threads of frass hang beneath the mine, caught in a loose net of silk.   Early instar larvae from the galleries are whitish; later instars have purplish spots and markings.
