Asteromyia gutierreziae Felt 



1916 Felt, E. P. N. Y. Ent. Soc. Jour., 24:179 



This species was reared by Mr P. H. Timberlake in May and June 

 19 14 from black, blisterlike galls on the slender flower stems of 

 Gutierrezia sarothrae collected near Salt Lake City, 

 Utah. The gall is very similar to that of Asteromyia car- 

 bo 11 i f e r a Felt and the adult presents many characters in common 

 with this widespread eastern species, from which it is most readily 

 separated by the third vein uniting with costa near the distal third 

 and the moderately stout, obtuse harpes with a conspicuous, eccen- 

 tric, quadrate, chitinous tooth. The eastern C. carbonifera 

 has the third vein uniting with costa near the basal half, while the 

 harpes taper to a decidedly slender apex bearing a conspicuous 

 quadrate tooth.

This fly was reared from a presumably typical oval, blister gall 

 on a leaf of Solidago rugosa, collected in October 1906, 

 the adult appearing May 16, 1907. The species probably winters 

 within the gall. Species of Torymus and Polygnotus were reared 

 from this gall. 



Gall. Oval, blisterlike and nearly 1 cm in diameter. Earlier* 

 it was presumably brightly ornamented with yellowish and shades 

 of pink or reddish. For a colored illustration, see Museum Bulletin 

 175, plate 1, figure 11. 



Female. Length 2 mm. Antennae dark brown; 22 segments, 

 the fifth with a length slightly greater than its diameter, the two 

 distal segments closely fused, subcylindric, broadly rounded apically; 

 palpi two-segmented; face rather thickly clothed with whitish 

 scales. Mesonotum dark brown, the submedian lines with the 

 lateral and anterior margins rather thickly clothed with golden 

 yellow scales. Scutellum brownish black, yellowish apically, 

 postscutellum dark brown. Abdomen dark brown or black, the 

 segments narrowly margined posteriorly with silvery white; ovipositor 

 pale orange; venter irregularly suffused with silvery white scales, 

 there being suggestions of submedian and sublateral whitish patches 

 on each segment. Wings hyaline, costa dark brown, the third 

 vein uniting with costa at the basal half. Halteres a pale yellowish 

 orange. Legs a nearly uniform dark brown or black, the posterior 

 legs with narrow, white annulations at the base of the first tarsal 

 segment; claws long, slender, strongly curved, the pulvilli as long 

 as the claws. Ovipositor about one-half the length of the abdomen, 

 the terminal lobes rather short, broadly rounded. Type Cecid.
