Explanation of Names
Chrysopa slossonae Banks, 1924
Adults are very similar in appearance to Chrysopa quadripunctata but differ in terms of wing venation. Larval traits differ more greatly, with C. slossonae adapted as a specialist of Prociphilus tesselatus, the woolly alder aphid, and C. quadripiunctata as a generalist. Larvae carry a debris packet of flocculence from their woolly aphid prey.(1)(2)
NC, NH, NY, VA(3); additional records possible in GA, ME, MD, WV(4)
Larvae are found exclusively on alder.(2)
Larvae are specialist predators of Prociphilus tesselatus, the woolly alder aphid.(2)
Hybridization with Chrysopa quadripunctata has occurred under laboratory conditions.(2)

Where sympatric, separation of adults of C. quadriguttata may not always be possible from photos alone.
