The gall's range is computed from the range of all hosts that the gall occurs on. In some cases we have evidence that the gall does not occur across the full range of the hosts and we will remove these places from the range. For undescribed species we will show the expected range based on hosts plus where the galls have been observed.

New species of gall-producing cecidomyidae
William Beutenmuller
(1907)
Lasioptera cornicola sp. nov.
Gall. Woody swellings on the twigs, branches or trunks on the dogwood (Cornus stolonifera [sericea]), measuring from about 6 to nearly 150 mm in length. When situated on the twig, the gall is considerably smaller than those on the larger branches and trunk. It sometimes gnarls the trunk from about one to six inches or more in length. Inside it is hard, woody, with many elongate chambers, each containing a larva.
Habitat: NY
The gall is rather common and may be found during all seasons of the year. The larvae overwinter and pupate in the galls, and the adults emerge during May and June.
