Case-building is energetically expensive and case-repair may be a viable alternative to rebuilding for caddisflies when the case is damaged. In this study, we damaged the larval cases of 3 Trichoptera genera: Lepidostoma spp.; Neophylax rickeri Milne, 1935; and Onocosmoecus unicolor (Banks, 1897). We manually damaged the anterior, middle, or posterior portions of the larval case. We measured ca...

Of the 30 extant orders of true insect, 12 are considered to be aquatic, or semiaquatic, in either some or all of their life stages. Out of these, six orders contain species engaged in entomophagy, but very few are being harvested effectively, leading to over-exploitation and local extinction. Examples of existing practices are given, ranging from the extremes of including insects (e.g., dipter...

An annotated list of 29 species from 18 genera and 10 families Trichoptera inhabiting rivers streams the Mountainous Shoria is given. All are recorded this region for first time. Two species, Dicosmoecus obscuripennis Banks, 1938 Rhyacophila lata Martynov, 1918, new Western Siberia. Moreover, westernmost locality narvae Navas, 1926, Neophylax ussuriensis (Martynov, 1914), Stenopsyche griseipenn...

Two new species of the caddisfly genus Cernotina Ross, 1938 (Polycentropodidae) are described from the lowland Amazon basin of Ecuador, Cernotina tiputini, new species, and Cernotina waorani, new species. These represent the first new species described from this region. We also record from Ecuador for the first time Cernotina hastilis Flint, previously known from Tobago, and present new Ecuador...

The replacement of native forests by exotic tree monocultures, such as those of Eucalyptus, decreases the quality of leaf litter inputs to streams and often reduces riparian cover, which can elevate water temperature. The combined effects of these stressors on the survival and performance of detritivores may be important, as detritivore species loss leads to reduced litter breakdown, a key ecos...
