The Gall Midges (Diptera: Cecidomyiidae) of Baccharis spp. (Asteraceae) in the United States
“

Larvae of Asteromyia spp. are found in blister galls of leaves or green stems of various Asteraceae...

Gagné (1968) considered a larval specimen from Baccharis in Texas to be Asteromyia gutierreziae because it was similar to larvae of that species. Two other kinds of larvae based on differences in the spatulae have since been found....Because the spatulae are so different, the larvae are placed here as Asteromyia sp. 1, sp. 2, and sp. 3.

...

Asteromyia sp. 2

The larval spatula of this segregate [of A. gutierreziae] has many fine serrations along the anterior edge. It is known from two specimens from Texas, each from a different species of Baccharis: B. pteronioides, Frijole Ranch, Guadelupe Mountains National Park...and B. bigelovii, Point of Rocks, 12 mi. W Ft. Davis, Jeff Davis Co....
