Heterarthrus leucomela (Klug, 1818)
< back
anal ring

 

Egg: laid at the tip of a leaf

Mine: August - September

Notes: A large blotch mine is formed from the tip of a leaf. The pupa is formed in the disc. The species has a long feeding period, more than two months (similar to Heterarthrus nemoratus). Completed mines may be found at the end of July in lower regions of Austria. The larva dorsally has a dark head and pigmentation on the prothorax. Ventrally it has the typical prothoracic 'collar' and spots on the meso- and metathorax. The legs are ringed. The anal ring has fine denticulations (as shown).
