Asteromyia tumifica

Protaplonyx sarcobati

Astictoneura muhlenbergiae

Edestochilus allioides

Beutenmüller (1907) described *Lasioptera tumifica* from stem galls on *Solidago rugosa* Mill. He actually had a mixed series of 2 species, *L. solidaginis* (Osten Sacken) and what is here considered *A. tumifica*...The galls of both species are found near the base of the stems of *S. rugosa* and *S. canadensis* [probably incl. *S. altissima*], but are quite different in structure. The gall formed by *L. solidaginis* ... is fusiform-cylindrical and is hard and woody, and that formed by *A. tumifica* ... is an outgrowth of the stem, usually to 1 side of it, and is soft and pithy in texture...

*A. tumifica* is closely related to *Asteromyia modesta* (Felt) and can be separated from that species by the larger adult size and shape of the larval spatula...The latter species is found in leaf blister galls...

...*A. tumifica* is the only one of the 8 species of *Asteromyia* to be found of woody stems; all the others are found in blister galls on the leaves or green stems of their various hosts.

*P. sarcobati* forms a biconvex swelling on the leaves of *S. vermiculatus* which somewhat resembles the galls formed on *Chrysothamnus* spp. and *Haplopappus* spp. by *Asteromyia chrysothamni* Felt. [these hosts are now mostly in the genus *Ericameria*, with some exceptions] 

The larva ... forms galls on *Muhlenbergia*. The gall, figured in Felt 1918: 225, is composed of imbricated leaves and the larvae lie singly or several together at the bases of the leaves forming the gall.

...reared from a stem gall on *Paspalum distichum*...there is a single larva in each gall...
