“…They construct typical odontocerid cases of sand grains and probably exhibit the typical habitat preferences and mode of living. The larvae of Barypenthus concolor do not select specific particle sizes for case building ( Moretti and Loyola, 2005 ).…”

The Neotropical caddisfly (Trichoptera) fauna is cataloged from a review of over 1,000 literature citations through 2015 (partial 2016) to include 3,262 currently recognized, valid species-group names in 25 families and 155 extant genera. Fourteen subspecies are included in the total as well as 35 fossil species and 1 fossil genus. The region covered includes all of Mexico, Central America, the Caribbean, and South America. Genus-group and species-group synonyms are listed. For each nominal species, information on the type locality, type depository, sex of type, distribution by country, and other pertinent taxonomic or biological information is included. Summary information on taxonomy, phylogeny, distribution, immature stages, and biology are provided for each family and genus where known. An extensive index to all nominal taxa is included to facilitate use of the catalog. The glossosomatid species Mexitrichia usseglioi Rueda Martín & Gibon, is transferred to Mortoniella comb. n.

“…According to some authors, the type of organic material used by caddisflies for case-building may vary depending on its abundance (Hanna, 1961;Otto & Svensson, 1980). Moreover, Moretti & Loyola (2005) demonstrated that larvae of Barypenthus concolor, a tube-case-building trichopteran, use particle sizes in the same proportions as they are available in the habitat to build their cases. All these findings imply great selective pressure operating on this behaviour.…”

Phylloicus sp. larvae live on leaf patches in slow flowing waters and build dorso-ventrally flattened cases from leaf pieces. We hypothesized that Phylloicus larvae are selective towards certain leaf species to build a more resistant case. We exposed Phylloicus larvae to equal-area leaf discs of three plant species from the Brazilian Cerrado (Myrcia guyanensis, Miconia chartacea and Protium brasiliense) and one non-native species (Eucalyptus camaldulensis). Phylloicus larvae built cases with discs of all plant species. However, discs of E. camaldulensis and M. guyanensis were used more (36.4% and 35.7%, respectively) than those of P. brasiliense (20.0%). Discs of M. chartacea were used in an intermediate proportion (28.6%). Selection was resource density-dependent, i.e. when P. brasiliense was offered at higher abundance, it was used more frequently by larvae (ANOVA, P \ 0.001). Plant species differed in leaf toughness, phenolic concentration and biomass:area ratio (Kruskal-Wallis, P \ 0.05). Larvae preferentially used leaves with higher phenolic concentrations (R s = 0.907, P \ 0.001) independently of toughness and biomass:area ratio. We suggest that Phylloicus selects for case-building leaves that are chemically protected against microbial degradation and shredder consumption, and this selection depends on leaf abundance. Our results also reinforce the importance of riparian resources and their diversity to the maintenance of aquatic consumers in tropical shaded streams.

We analysed the microhabitat preferences of caddisfly species in four rivers in north-western Spain. In each river, we sampled five sites with different types of substrate. These sites were characterised in situ according to the predominant material type (macrophytes, moss, pebbles and sand). A one-way ANOVA was used to test for significant differences in species abundance among substrates, and a nested ANOVA was used to test for significant differences in physical and chemical variables among rivers and sampling sites. A similarity percentage-species contribution analysis was performed to estimate the contribution of each species to the characterisation of each substrate. We observed significant differences in the abundance of seven species (Drusus bolivari, Glossosoma privatum, Larcasia partita, Micrasema longulum, M. servatum, M. gr. moestum and Sericostoma sp.) among substrates, confirming that these species have substrate preferences. According to similarity percentage-species contribution, the species that contributed most to differences were as follows: for sand, Sericostoma sp.; for macrophytes, Rhyacophila adjuncta, Hydropsyche ambigua, Sericostoma sp.; for moss, Micrasema gr. moestum, M. servatum, M. longulum, Hydropsyche tibialis and R. adjuncta; and for pebbles, Sericostoma sp., Larcasia partita and H. tibialis. These preferences can be explained by the fact that different species use different materials from the substrate to build their cases and also as a source of stability, protection and food.
