Aulacidea tragopogonis: larva in gall

larva in the gall

gall

Small semiglobular galls, usually several together, on the stem near the root collar or on the roots, each with one gall chamber. Larva solitary. Univoltine, pupation and hibernation in the gall.

Roskam, and Redfern & Shirley state that the same species is responsible for elongate flower heads. Because other sources do not mention this, confirmation is needed.

hostplants

Asteraceae, monophagous

Tragopogon dubius & subsp. major, porrifolius, pratensis & subsp. orientalis.

notes

the larva is described by Gómez Sanchez (2008a).
