Euschistus crenator
This record describes Euschistus crenator (species). Recorded family: Pentatomidae. Recorded order: Hemiptera.
Identification and Appearance
Dorsum brown with antennae yellow but with dark spotting on first antennomere and femora. Humeri obtuse to acute, but if acute they tend to be retrorse. Can only be separated from E. quadrator by male genitalia. Both co-occur in TX (where E. quadrator is more common) and in FL (where E. crenator is the more common). see

Habitat and Range
Geographic Range
E. c. crenator : FL, W.Indies, northern S.America • E. c. orbiculator CA‒TX‒Mesoamerica • from Rolston it is clear that the nominal subspecies is the form occurring in n.S.America and W.Indies, and it is probably the form found in FL
Diet and Behavior
Diet: Brailovsky et al. (1992) report this species feeding on sedges; Maes (1994), on crops in Nicaragua, incl. beans, cotton, and tomatoes

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