Explanation of Names
Chrysopa quadripunctata Burmeister, 1839
quadripunctata = from the Latin quādrī ('four') + punctāta ('spotted')

Chrysopa slossonae Banks, 1924
slossonae = named after Anna "Annie" Trumbull Slosson, an American entomologist who collected syntype material.
Identification
Chrysopa quadripunctata and C. slossonae are reportedly very similar species apart from minute traits of wing venation, and are even capable of hybridization under laboratory conditions. Adults are very similar apart from 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. The larvae of C. quadripunctata are known from various plants (including oak species) whereas C. slossonae are collected only on alder.(1)(2)
Range
NC, NH, NY, VA (known range of C. slossonae; C. quadripunctata is widespread)(3)
Remarks
Where sympatric, separation of adults may not always be possible from photos alone.
