Oak Spittlebug
Clastoptera querci
This record describes Clastoptera querci (species). Recorded family: Clastopteridae. Recorded order: Hemiptera.
Identification and Appearance

This species was just described (Sept. 25, 2020). This species showed up in Florida about a decade ago, possibly from Cuba. Primary hosts are oak for nymphs and adults. The red markings on the vertex and anterior pronotum are distinctive, as is the greenish pronotum in many specimens. This species also has a distinctly outlined bulla (apical wing callous), whereas C. obtusa has a more diffuse bulla. (pers. comments from V. Stanton to K. Kittelberger)

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Clastoptera querci. 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.
