Stoneflies - Plecoptera: Chloroperlidae of Gunnison County, Colorado
Paraperla frontalis(Banks, 1902)
Updated 21 May 2016
Large for a chloroperlid. Pale and thin with eyes set very far forward. The illustration on the right is from Needham and Claassen's classic stonefly study published in 1925.
Creeks, rivers and cold lakes. Nymphs live in the hyporheic zone or the water between the gravel and rocks in the bottom of the stream.
Dewalt and Stewart (1995) collected nymphs infrequently in winter months among marginal substrates of streams. Less than 10 adults were collected in early June during the 3 year study on the Rio Conejos river. Baumann et al (1977) note that adults can be collected from April to early August.
Knight and Gaufin (1966) collected this species between 7200 and 9600 feet elevation. Kondratieff and Baumann note that this relatively common species is rarely collected unless you use a beat sheet or examine debris along streams.
The genus Paraperla was previously included in Perlinella. Older publications may refer to this species as Perlinella frontalis.

Quoted from pages 394-395: "This is a relatively common species, but adults, especially males, are rarely collected unless by using a beating sheet or examining streamside debris piles along Mountain and Plateau streams and rivers. Nymphs are hyporheic until near emergence."

The authors report P. frontalis from the hyporheic zone of the Flathead River in Montana, USA. Figure 1 is a photo of P. frontalis nymphs from the hyporheic zone of the Tobacco River. From nymph collections, they report that P. frontalis spends 2 or 3 years in the hyporheic zone growing to nearly 2cm in length before emerging as adults.

Abstract:Eggs and larvae of Paraperla frontalis (Banks) and P. wilsoni Ricker are described from scanning electron micrographs. The eggs of both species are coarsely punctate over the entire chorion except for a narrow ring which surrounds the sessile collar, however, punctations are larger and more conspicuous on P. frontalis eggs. Larvae of P. wilsoni are similar to those of P. frontalis, but lack the lacinial pecten row and vertical cercal fringe found in the latter species.

Quote about the genus Parapela from page 213: "Western Nearctic; the 2 species occur from the Yukon to California and New Mexico. Adults are brown, 16-20 mm. They emerge March-August, depending on elevation and latitude. Nymphs occur in the hyporheal beneath and beside larger streams, and are collected in surface layers only just prior to emergence. Nymph sizes before and after emergence suggest 2-3 year, semivoltine life cycles. "

Part of abstract: " Both chloroperlids, Kathroperla perdita and Paraperla frontalis, had di-phasic male calls, with 6.1 ± 0.7 and 74 ± 10.6 beats, respectively, in the first phases, and with distinctly different beat intervals. "

Abstract: "Larval structures diagnostic of several Plecoptera families, subfamilies or genera are described and illustrated. They concern the following: distinction of larval Leuctridae from Capniidae; an additional apomorphy of Nemouridae; a synapomorphy of Perlidae and Perlodidae; monophyly of each of the two subfamilies of Chloroperlidae, and the generic limits among Chloroperlidae: Paraperlinae. Paraperla lepnevae Zhiltzova is transferred to Utaperla. Some comments on Notonemouridae are included."
