Anoterostemma ivanhofi Lethierry, 1876
Description & Identification
A. ivanhofi has a squat body outline, adults being only 2.5— 4.5mm long.
As with all leafhoppers, the hind tibiae have rows of spines running along their entire length.
A. ivanhofi are brachypterous i.e. they have very shortened forewings, and hindwings that are reduced in size or completely absent. The abdomen is entirely black apart from the terminal segments; the background colour of the head, thorax and wings is light brown with distinctive dark brown/black markings.

Biology & Ecology
Little is currently known about the ecology of Anoterostemma ivanhofi in the UK. The main population in Scotland is on
the upper level of a saltmarsh in extensive stands of saltmarsh rush, Juncus gerardii, which is assumed to be its host
plant. The brachypterous nature of adults in this species
means that their ability to disperse will be severely limited.
Adult females are presumed to lay eggs in their host plant
during the summer or autumn. It is not known what life
history stage overwinters. Nymphs are likely to pass through
five moults before emerging as adults in early summer.
UK Status: Present
Anoterostemma ivanhofi is a leafhopper that is known in Britain from only a small area near Kirkcudbright in Scotland.
As with all froghoppers and some of the larger leafhoppers, A. ivanhofi feeds on the liquid contents of the xylem vessels of its host plant. As such, it is a potential vector of the bacterium Xylella fastidiosa which has caused the death of many olive trees in southern Europe, although this disease has not been detected in the UK.
