“…K. kuscheli spans from near 38°to 51°S, where it has been found in piedmont streams at low altitude (ca. 300 m a.s.l., MCLELLAN, 2001;CAM-POS et al, 1984). However, at low latitude it is limited to low order reaches (WAIS, 1987;ALBARIÑO, 1997;MISERENDINO, 2000;ALBARIÑO, pers.…”

“…For instance, N. archiplatae is absent in low reaches of piedmont streams and rivers (ILLIES, 1963;WAIS, 1990;ALBARIÑO, 1997;MISERENDINO, 2000). While the taxonomy of the genus Klapopteryx (Austroperlidae) has recently been revised (MCLELLAN, 2001), the genus Notoperla (Gripopterygidae) is currently under study (IAN MCLELLAN, pers. comm.…”

Feeding plasticity of the Andean plecopteran Klapopteryx kuscheli and Notoperla archiplatae larvae was assessed through a field experiment using enclosures. K. kuscheli has previously been described as a shredder and N. archiplatae as a scraper. Further information on gut contents from different populations supported those results. In the experiment, larvae of both species were exposed to contrasting food items: leaf litter and periphyton. Consumption, growth and the efficiency of food conversion were measured. K. kuscheli was able to feed on periphyton, though it did not grow. N. archiplatae failed to feed on leaf litter. While K. kuscheli might be considered a facultative shredder, N. archiplatae functions as a specialist scraper. The natural distribution and seasonal abundance in two small streams showed contrasting habitat use of both species. N. archiplatae inhabited high velocity runs and riffles underneath large substrates while K. kuscheli presented a higher habitat plasticity. Implications of those results for ecosystem function are discussed.

“…Although this phenomenon appears to characterise the adult stage of austroperlids, with colouration in the aquatic larval (nymph) stage ranging from olive-green to brown (Fig. 4; Illies 1969;McLellan 2001), bright yellow markings described in mature nymphs of Austroheptura neboissi and Austropentura victoria (Illies 1969) may also serve an aposematic function during the transition to the terrestrial adult stage. Sundberg (1979) and Edmunds (1987) proposed that the existence of aposematism requires evidence that the organism is conspicuous, has one or more defence mechanisms against predators and is learnt to be avoided by some predators due to its appearance.…”

Evidence for aposematism in a southern hemisphere stonefly family (Plecoptera: Austroperlidae)

Aposematism is a phenomenon in which defended prey advertise their unprofitability to predators through conspicuous signals. Aposematic (warning) colouration is widespread across numerous insect orders but rarely occurs in insects that inhabit aquatic environments where conditions can impose constraints on visual signal transmission. In the semi-aquatic insect order Plecoptera (stoneflies), only the terrestrial adult stage of Austroperla cyrene (Austroperlidae) from New Zealand has been suggested to possess aposematic colouration, associated with the presence of hydrogen cyanide and documented unpalatability to predators. Here, we review evidence for the occurrence of aposematic colouration in Australian and South American Austroperlidae based on a synthesis of taxonomic literature and studies examining feeding preferences of predators in aquatic environments. Contrasting black, white and yellow colouration occurs commonly in adult Austroperlidae, and nymphs of several surveyed species were found to be aversive to predators, together suggesting that aposematism may be widespread in this family. The wider prevalence of aposematism in Austroperlidae should be examined further by directly testing the palatability of various species to predators and by analysing the chemical compositions of their defensive secretions. Austroperlid stoneflies offer new potential for understanding the evolution of aposematism in ecological and phylogenetic contexts that have not yet been explored.

“…Then, it is possible that pit-fall traps effectively caught more males (all brachypterous) than females of K. kuscheli. Brachyptery is more common in permanent aquatic habitats (Harrison 1980) and frequently associated with an increase in altitude and latitude, particulary where insects are exposed to cool temperatures and high winds (McLellan 2001).…”

The temporal dynamics in density, life histories, and emergence patterns were described for the first time for five Plecoptera species in tributaries of the Futaleufú River in Patagonia, Argentina. Benthic samples and adult collections were made in five low order Nothofagus forested streams. Four species of Gripopterygidae; Aubertoperla illiesi, Notoperlopsis femina, Antarctoperla michaelseni and Senzilloides panguipulli had simple, highly synchronized univoltine life histories. The austroperlid Klapopteryx kuscheli takes more than two years to develop. Emergence periods of most of the species were concentrated in late spring and summer (October to February), which suggests seasonal and synchronized life histories. Most N. femina adults were collected in mid spring indicating this species emerged first, whereas S. panguipulli emerged last from January to April. Aubertoperla illiesi showed a slightly delayed emergence at the high elevation site (La Hoya Stream) when compared to a piedmont stream, suggesting that temperature was an important control. Although we were unable to describe the life history of Limnoperla jaffueli (Gripopterygidae) its adult emergence period was November to January. Life histories of Plecoptera species in the studied streams seem to have a high degree of seasonality at least at this latitude, and are possibly determined by predictable temperature patterns and discharge regimes. This first contribution on the life histories of Plecoptera species helps us to better understand the dynamics and functioning of pristine but fragile aquatic environments in Patagonia.
