Idiocerus catalinus
This record describes Idiocerus catalinus (species). Recorded family: Cicadellidae. Recorded order: Hemiptera.
Identification and Appearance

Smaller than rotundens DeL. and C., the smallest American species in the genus. Vertex pale, usually without spots, elytra pale with a rusty brown band across the middle and similar marking in the claval area basally. Form of rotundens nearly, highly ornamented as in apache . Vertex half longer in males than in females. Female ultimate segment long, only onehalf wider than its median length. Female pygofers short and broad and the ventural surface flattened, the ovipositor exceeding the pygofers by a little more than its width. Male antennal disc small, long oval on a filament about three times as long as the disc. Male ultimate segment relatively short but curved around pygofers so that the lateral rounding lobes are vertical, and give the appearance of a quadrate emargination and a strong median tooth. Male pygofers relatively small and narrow and acutely pointed. Color, pale creamy or ivory with a reddish-brown band across the elytra and similar markings around the disc of the pronotum and scutellum, running back on the elytra as a smoky area in front of the large ivory saddle. Female face with a brown band between the ocelli and the faint spots on vertex. Male face pale above with the spots nearly obsolete, the inner two pairs of stripes narrow, brown, the outer pair broad and black. (Ball & Parker, 1946)

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Idiocerus catalinus. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
