Eriocrania cicatricella
Betula, Belgium, prov. Namur, Lives-sur-Meuse; © Jean-Yves Baugnée
Betula pubescens, Dwingelderveld; head and thorax, dorsal
When strongly lighted from below it appears that two parasioid eggs are attached to the larva.
Full grown larvae are entirely white; the head is very weakly chitinised, only the mouthparts are light brown (Bengtsson, 2008a). According to Hering (1957a) young larvae have a black head and pronotum!
