Iteomyia major is a gall midge which forms galls on willows (Salix species). It was first described by Jean-Jacques Kieffer in 1889.
Description of the gall
The gall is a coalesced group of 2–10 hard round galls, on the midrib or side vein and are equally prominent on either side of the leaf. [1] Each gall has a single larva, initially white and later orange or red. [2] There is a single generation each year and pupation takes place in the soil. [3] Females prefer to lay their eggs on the ″broad-leaf willows″ and the galls are found on sallows, or their hybrids, which include bay willow ( S. pentandra), bitter willow ( S. elaeagnos), dark-leaved willow ( S. myrsinifolia), eared willow ( S. aurita), goat willow ( S. caprea), gray willow ( S. glauca), grey willow ( S. cinerea), purple willow ( S. purpurea), tea-leaved willow ( S. phylicifolia) and woolly willow ( S. lanata). [3]
Similar species
Iteomyia capreae galls are small, hard, green pouches, up to 4 mm in diameter and, as they mature, have a reddish or purplish tinge. They are not as prominent on the lower leaf surface, having red-rimmed conical pores. [1]
Distribution
Recorded from Great Britain (England, Scotland and Wales) and the Netherlands. [2] [3]
