Myzocallis walshii
This record describes Myzocallis walshii (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
Specimens found earlier in the year are largely yellow with black pigment at apices of antennal segments and some weak pigment on foretibiae and on costal margin of forewing; later in the year pronotum with black pigment on each side, costal margins of fore- and hind wings black, foretibiae and tarsi black and meso- and metatibiae mostly pale, pigmented on apical portions. Similar in appearance to M. granovskyi , but M. granovskyi has black tibiae on all legs, and the apices of the femora are also black.

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