Sitodiplosis mosellana (Géhin, 1857)
wheat midge
on Triticum
gall
An orange larva lives in a spikelet, that does not show signs of damage, yet the seed remains undeveloped. Univoltine; pupation and hibernation in the soil in a silk cocoon.
Only in the first and second instar the larva does feed. The third-instar larva remains immobile within the dried larval skin of the second instar, that functions as a temporary cocoon. After a shorter or longer time the larva leaves the temporary cocoon and drops to the ground.
