This species is similar to Macrophya annulata but has a conspicuous white fleck on the hind coxa (on the sclerite, not the membrane). The red girdled abdomen may be infuscate in the middle on the dorsal surface, or may be absent altogether. The species is associated with wooded areas.
Larvae are present between July and September on raspberry, blackberry, creeping cinquefoil and possibly other rosaceae. They develop over an eight to ten week period before entering a two to three week eonymph stage in leaf litter. It then burrows to hibernate under ground.
Size: 10 - 12.5mm
