This record describes Dictyonissus nigropilosus (species). Recorded family: Tropiduchidae. Recorded order: Hemiptera.
Identification and Appearance
There are only two species in the genus. They resemble each other closely in color, size and general features. They are easily distinguished by the presence of pitch-black hairs on body and tegmina in nigropilosus , together with the angulate vertex and the very narrow frons without any black markings. D. griphus has golden or light hairs, the anterior margin of vertex distinctly rounding and more produced beyond eyes and a broader frons with a row of black spots indicated in each lateral disk. Described from 3 males and 1 female. Holotype male and allotype female and two male paratypes taken at George West, Texas, July 1, 1936, collected by R. H. Beamer.

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