This insect occurs in a purplish, somewhat conical, thick walled, apical bud gall with a length of about 1 cm. and a diameter of 3 mm.This gall develops later than that of Walshomyia texana ... When mature the tip splits, forming four or more irregular lobes, the adult escaping from the apex. This species has been reared from Juniperus monospermum from galls collected near Denver, Colo., in 1914, by Professor E. Bethel and from similar galls on Juniperus utahensis [J. osteospermum] collected by Professor Bethel at Gilluly. Utah, and also from apparently identical galls on Sabina sabinoides [J. ashei] collected by J. T. Patterson in April, 1919, near Austin, Texas.
