Evacanthus interruptus Linnaeus, 1758
Description & Identification
Adults are typically 5.5 - 6.5mm long; females are somewhat larger than males because the tip of the abdomen protrudes significantly beyond the tips of the wings.
E. interruptus is very strikingly coloured black and yellow so is
readily distinguished from all other leafhopper species. The
black patterning is variable and in very rare cases the forewings are entirely yellow. As with all leafhoppers, the hind tibiae have one
to three rows of spines running along their entire length. (Harkin & Stewart 2019)
Biology & Ecology
E. interruptus can be found in a variety of habitats, but most
frequently in ones that are moist to wet, from open grasslands and meadows to species-rich fens and marshes. The
host plants include a variety of herbaceous species.
Females lay eggs in the autumn and the nymphs emerge the
following spring. Nymphs moult five times before emerging
as adults. Adults can be found between June and October. (Harkin & Sterwart 2019)

Worldwide Distribution
UK Status: Present
Evacanthus interruptus is a rather local leafhopper but with a widespread distribution across Britain and Ireland. (Harkin & Stewart 2019)
Vector Status
As with all froghoppers and some of the larger leafhoppers, E. interruptus 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.
