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.

The catalpa midge. Cecidomyia catalpae Comstock
H. A. Gossard
(1908)
Mr. Houser in Bulletin 194 of this Station says: "During the early summer, the tender growing tips of the catalpa become swollen and in time blacken at the point of injury. During the early part of the season the injury is usually found three or four inches below the tip, and at a lesser distance during late summer when the tree is growing less rapidly. The tip above the injury dies. Following the death of the tip in early summer, the next node below develops one or more branches, and frequently a cluster of leaves, giving the tree a bushy growth. The ultimate result, after continued topping, is a stunted, crooked, forked growth."
[Gossard seems to have identified this with Cecidomyia catalpae [syn: Contarinia catalpae], but Gagné (1989) lists this damage separately, assigning it to an undescribed midge.]
