Xenostrongylus histrio Wollaston, 1854
Short gallery, continued in, and mostly overrun by, a later blotch of two square cm at most. The blotch is full-depth, except its centre, which is lower-surface and therefore remains green. Here the larva withdraws during feeding pauses. Pupation external.
Larvae from March on.
