Superfamily CICADOMORPHA

Antennae arise from between the pair of compound eyes.

10. Family CERCOPIDAE (froghoppers)

Small to medium-sized, very active bugs with the hindlegs adapted for jumping; ocelli (two) present in adults; adults of some species are superficially frog-like; hind tibiae cylindrical and bearing just a few stout spines (Fig. 29) (cf. family Cicadellidae); veins 1A and 2A of forewings separate throughout their length (Fig. 30a) (cf. family Delphacidae). Nymphs develop within a protective mass of froth (often called 'cuckoo-spit'), a secretion produced from the anus and through which air bubbles are forced from a special canal by abdominal contractions.

EXAMPLES: Aphrophorinae - Philaenus spumarius (common froghopper); Cercopinae - Cercopis vulnerata (red & black froghopper).

11. Family CICADELLIDAE (leafhoppers)

Small insects, with hindlegs of the very active adults adapted for jumping; ocelli (two) present or absent; hind tibiae angular and bearing one or more rows of spines (Fig. 31) (cf. family Cercopidae); veins 1A and 2A of forewings separate (see Fig. 30a) (cf. family Delphacidae); female ovipositor adapted for lacerating plant tissue into which eggs are laid. Nymphs active and free-living.

EXAMPLES: Aphrodinae - Aphrodes bicinctus (strawberry leafhopper); Evacanthinae -Evacanthus interruptus (hop leafhopper); Typhlocybinae - Eupteryx melissae (chrysanthemum leafhopper).

Superfamily FULGOROMORPHA

Antennae arise from below the compound eyes.

12. Family DELPHACIDAE (planthoppers)

Leafhoppers characterized by the large, moveable apical spur on each hind tibia (Fig. 32); veins

1A and 2A of forewings Y-shaped, being united distally (Fig. 30b).

EXAMPLE: Javesella pellucida (cereal leafhopper).
