Aizobius sedi (Germar, 1818)

on Hylotelephium, Sedum, Sempervivum

mine

The weevil generally lives as a stem borer, but also as a leaf miner. It then makes a narrow, hardly widening, weakly branched, brown full depth corridor that ends upon the midrib. Sometimes a small blotch is formed there, or the larva works through the midrib towards the stem. The larva pupates in a globular cocoon that either lies in the stem or in the small blotch on the midrib (Hering, 1957a; Scherf, 1964a).
