Identification
Members of Paraperla can be distinguished from other Chloroperlidae by their placement in the Paraperlinae. The specific epithet 'frontalis' in P. frontalis refers to a frontal characteristic, though detailed diagnostic features for the are not well documented in available sources. As green stoneflies, they likely share the 's general characteristics of relatively small size and pale green to yellow coloration, though -level identification requires examination of genitalic structures.

Habitat
The Paraperla frontalis is known as the 'hyporheic sallfly,' indicating specialized association with hyporheic zones—the saturated sediments beneath and alongside stream beds where groundwater and surface water mix. This suggests the occupies aquatic rather than open water surfaces.
Distribution
Records indicate presence in western North America including Alberta, Alaska, British Columbia, California, Colorado, and likely additional regions given the 's distribution. The appears restricted to the Nearctic region.
Ecological Role
As stoneflies in hyporheic , in this likely contribute to nutrient cycling within groundwater-surface water interface zones. Their presence indicates intact subsurface hydrological connectivity.

Taxonomic placement
Paraperla is the type of Paraperlinae, indicating its significance in the higher classification of Chloroperlidae. The subfamily was established to accommodate genera with distinct morphological and ecological characteristics.
Etymology
The name combines the Greek prefix 'para-' (meaning beside or near) with 'Perla,' the type genus of Perlidae. This reflects its historical taxonomic proximity to that group before assignment to Chloroperlidae.
