upon disturbance the larvae jumped around actively and formed a dense clump
here as well the larvae sometimes were accompanied by cf. Systasis encyrtoides.
larva of cf. Systasis encyrtoides in cocoon.
Larvae in the pods that have some, c. 2 mm large warts, usually in the distal half; the inside of the pod is not lined with mycelium. Larvae gregarious,shining yellowish white; they can jump. Univoltine, hibernation in the soil.
Parnell cites four species of Chalcidoidea of which the larvae occur as carnivores in the galls of C. pulchripes. About one of them, Systasis encyrtoides, he writes that the larva hibernates in a “siken cocoon” and pupates after the winter. Because in Chalcidoidea cocoons are a rare phenomenon, it is probable that this is the species of the non-cecidomyiid larvae in the pods.
