Sinea complexa
This record describes Sinea complexa (species). Recorded family: Reduviidae. Recorded order: Hemiptera.
Identification and Appearance
The only Sinea of the Southwest with spines on both lobes of pronotum and fore femur strongly swollen distally. S. incognita from the Midwest will also match this description and is most easily separated by range. S. integra from Mexico has a more cylindrical fore femur, and other North American species have spines only on the anterior lobe of the pronotum.

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