Explanation of Names
Named in honor of Frank Haimbach who collected the first specimens in Cincinnati, Ohio. (1) Haimbachia Dyar, 1909 and Zelleria haimbachi Busck, 1915 are also named for him.
Wingspan 13-17 mm. (1)
Adult - see original description on Print References.
Eastern half of the United States and adjacent Canada. (2)
The larvae bore into the buds and young shoots of cottonwoods, such as Populus balsamifera and P. deltoides, as well as some poplars (which are in the same genus).
Life Cycle
Overwinter as larvae either in silk covered shallow pits excavated in healed-over borer entrance holes, in th margin of corky bark ridges below leaf bases, or in depressions of leaf scars.(3)
When young larvae resume activity in spring they enter the tender, new shoots to feed and complete their development. The older overwintering larvae kill the bud and up to 10" of the terminal.(3)
4-5 generations in the Miss Delta region.(3)
The larvae are among the most destructive pests of cottonwoods in our area.
