This record describes Cyllecoris histrionius (species). Recorded family: Miridae. Recorded order: Hemiptera.
Identification and Appearance

The adult is a strikingly marked and elongate bug reaching a length of 6 to 8 mm. The largely black pronotum is strongly narrowed at the front, forming a distinct collar which is marked with yellow or white. The antennae are red tipped. This species can be identified with care but there are similar species that it could be confused with. Adults are found mainly from late May to July. A largely predatory bug, feeding on other small animals such as aphids and bark flies, as well as unopened oak catkins and young acorns.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Cyllecoris histrionius. 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.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
