Issid Planthoppers Family Issidae

Identification: Body not particularly wedge-shaped. FW often short, the costal area without numerous cross veins. Hind tibiae with spines on sides in addition to apical ones.

Many species in this group are short-winged and some have a weevil-like snout.

FULGORID PLANTHOPPERS Family Fulgoridae Not illus. Identification: Anal area of HW with many cross veins (such cross veins are lacking in remaining families).

This group includes some of our largest planthoppers, but they are not very common. Most of them are brownish.

DERBID PLANTHOPPERS Family Derbidae Identification: Terminal segment of beak about as long as wide (remaining families have this segment longer).

Most derbids have long narrow front wings and are rather delicate in build; many are brightly colored. These planthoppers feed on woody fungi.

DELPHACID PLANTHOPPERS Family Delphacidae Identification: Hind tibiae with a large apical spur.

This is the largest family of planthoppers. Its members are often very common insects. Most of them are quite small and many are short-winged.

ACHILID PLANTHOPPERS Family Achilidae

Identification: Body flattened. FW overlap at apex, and the claval suture does not reach wing margin.

Most achilids are brownish, and occur in coniferous forests. Nymphs usually live in dead wood and under bark.

DICTYOPHARID PLANTHOPPERS Family Dictyopharidae Identification: Head strongly prolonged anteriorly, or front with 2 or 3 carinae (keels), or tegulae absent and claval suture obscure. Median ocellus lacking.

Most dictyopharids have the head produced forward into a long, slender, beaklike structure. If the head is not so produced, the body is usually oval and the front femora are broad and flattened.

CIXIID PLANTHOPPERS Family Cixiidae Identification: Head little or not at all extended anteriorly; front with only a median carina (keel) or none. Median ocellus often present. Tegulae present. Claval suture distinct.

This is a relatively large group. Its members have membranous front wings, often with dark spots along the veins.

KINNARID PLANTHOPPERS Family Kinnaridae Not illus. Identification: Pale-colored, 3-4 mm. Similar to cixiids but abdominal terga 6-8 with wax-secreting pores. Vertex narrow and troughlike, narrower anteriorly.

Six species in the genus Oeclidius occur in the West.
