gall and exuvium
fresh gall (left), opened gall (top right) and vacated gall (bottom right) (from Mik, 1885a).
The larva usually needs two years for its development, but sometimes just one. In the first case, by far the most common, an artichoke gall is formed of 1-3 cm; its centre consists of a few broad thin scales that enclose a cavity in which one orange larva lies. When the larva develops in one year essentially only this inner part of the gall is formed, less than 6 mm in size. Pupation in the gall.
the prosternum has no spatula (from Möhn, 1955a)
Mesopolobus aspilus; Torymus nigritarsus.
