Purshivora nigranervosa
This record describes Purshivora nigranervosa (species). Recorded family: Psyllidae. Recorded order: Hemiptera.
Identification and Appearance
Wings with veins heavily darkened Given that the genae are short and non-conical and that the metatibial spurs apparently number >5, C. nigranervosa 's placement in the genus Cacopsylla seems to be in error. Jensen compares the species to Psylla phoradendri , now treated under Freysuila , a genus which is also primarily associated with Caesalpinioid legumes. It's currently unknown if this relationship is more than artificial. -C. Mallory

Diet and Behavior
Diet: California collections from Senna armata & Hoffmannseggia microphylla (Fabaceae: Caesalpinioideae); Bugguide photos and obesrvation of nymphs from Senna armata seem to confirm this . Percy et al. suggest that the host could be "possibly Cercocarpus " but there doesn't seem to be any support for this claim.

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