Explanation of Names
Livia Latreille 1802
10 spp. in our area(1), 25 spp. total(2)
Head (including eyes) greatly flattened, not deflexed, vertex longer than broad and usually somewhat rectangular in shape, cleft anteriorly; antennae as long as head width, segment 2 longest and broadest; wings thickened (1). A clear shot of the antennae (showing the relative size of segments and the terminal setae) is often very useful in diagnosing species of this genus.
Holarctic (1)
Hosts: Carex (sedges) and Juncus (rushes) (1)
Life Cycle
Several spp. overwinter as adults, sometimes taking shelter on coniferous trees. Eggs are inserted into the base of growing Carex or Juncus shoots; nymphs feed on developing shoots, forming galls (1).
