True Bugs, Cicadas, Hoppers, Aphids and Allies

Order Hemiptera

The True Bugs, Cicadas, Hoppers, Aphids and Allies (Order Hemiptera) includes 7,349 species across 120 families and 1,727 genera in our directory.

About True Bugs, Cicadas, Hoppers, Aphids and Allies

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.

Economic Impact

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.

Ecological Role

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.

Species in Hemiptera (7,349)

Cyrtolobus maculifrontis

Membracidae

An incredibly variable species; perhaps the most variable in the genus. Certainly worthy of closer study.

Cyrtolobus maxinei

Membracidae

Identification: MALE: FEMALE: In life, the coloration of the species is described as green as opposed to the yellow seen in dried specimens. The male and female of this species have not been associated with absolute certainty beyond the fact that the

Cyrtolobus oblongatus

Membracidae

Cyrtolobus arizonae , C. frigidus , and C. oblongatus are three western species that are superficially nearly identical. It is unclear if there are any good ways to separate them from one another.

Cyrtolobus ovatus

Membracidae

Likely two different entities under this name, a northern and southern, according to Mark Rothschild

Cyrtolobus pallidifrontis

Membracidae

It was previously incorrectly noted that this is the only Cyrtolobus with a dark band across the middle of the wings. A few other species exhibit this character including the similar C. gramatanus and the dark band most often only applies to the fema

Membracidae

This species is very similar to Cyrtolobus maculifrontis and females may be difficult to differentiate between the two species.

Cyrtolobus vanduzii

Membracidae

Currently understood to be a highly variable species, but that may eventually change
