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.
