Cochlorhinus opertus
This record describes Cochlorhinus opertus (species). Recorded family: Cicadellidae. Recorded order: Hemiptera.
Identification and Appearance
From Studies on insects of the Redwood Empire I: New Phytophagous Hemiptera from the Coast Range mountains, self-published by Bliven 1955 (Eureka, CA): Runs to couplet 4 in Beamer's key where it differs from unispinosus in the long male plates and from the alternative in the long deeply notched female segment. Resembling stygicus in general form, head a little sharper, color pattern distinctive. Male plates very similar to those of Drionia nigra while the female seventh sternite is scarcely distinguishable from that of Calonia signata .

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Cochlorhinus opertus. 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.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
