Changes in larval density and movement behavior of a commensal midge, Nanocladius (Plecopteracoluthus) sp. #4, were monitored for 26 weeks in recirculating laboratory streams. Adults were captured at emergence, sexed, and weighed to assess the effect of larval density and movement behavior on emergence success and adult size. The density of midges on hosts declined with time and coincided with a springtime increase in larval movement frequency. Midges residing on hosts with high spring…

Infestation intensity and prevalence of an ectosymbiotic midge under variable environmental and host conditions
Prevalence and infestation intensity were high in both years of the study, but neither infestationintensity nor prevalence was correlated with host population density across sites, contrary to the authors' expectation.
Living on a catfish: nested occupation of ectosymbiotic chironomids on host body
It was found that suboptimal sites on the host body were usually only occupied by a symbiont when the optimal sites were already occupied and sites occupied by larvae on small host body surface were a subset of the sites occupied on large hosts.
Seasonal Differences in Predator-prey Behavior in Experimental Streams
Season can influence the outcome of predator-prey interactions, and environmental context, as well as predation mode, is critical to predicting predation effects in macroinvertebrate communities.
O predador beneficia sua presa? Comensalismo entre Corynoneura Winnertz (Diptera, Chironomidae) e Corydalus Latreille (Megaloptera, Corydalidae) no Sudeste do Brasil
It is remarkable that by attaching to larger body size predators, prey could become free from predator bouts and could also be transported by them.
Records of chironomidae larvae living on other aquatic animals in Brazil
In this study, we report forty-nine cases of Chironomidae larvae living on other animals in Brazilian aquatic ecosystems, including a wide range of hosts, such as hydrozoans, snails, insects and

Consequences of larval intraspecific competition to stonefly growth and fecundity
It is concluded that competition between early-instar stonefly larvae results in an asymmetry of body sizes, but that competitive effects are reduced as larvae slow or cease feeding before emergence.
Effects of Density and Microdetritus Enrichment on the Growth of Chironomid Larvae in a Small Pond
The results indicate that the larvae of the two species can coexist stably at densities high enough to result in substantial intraspecies competition, and that differences associated with their mode of feeding contribute to resource partitioning.
Pupation, emergence and fecundity of phoretic Epoicocladius ephemerae (Chironomidae)
Analysis of the emergence data of the midge and of the mayfly support the hypothesis that some larvae of E. ephemerae use the fullgrown nymphs as pupation sites, probably because the emerging hosts carry the pupae to the water surface.
Population ecology of the commensal chironomid Epoicocladius flavens on its mayfly host Ephemera danica
Enhanced chance of survival, rather than the supply of detrital food particles which collect on the host's body, is considered as an important benefit to accrue to E. flavens from this commensalism.
The effect of host density on the success of commensalistic Epoicocladius flavens (Chironomidae) in utilizing streamliving Ephemera danica (Ephemeroptera)
The only means by which to increase the relationship between population size and the probability of a female E. flavens of obtaining a mate is by dispersal, since such behaviour will increase the effective population size.
Territoriality in Filter-Feeding Caddisfly Larvae: Laboratory Experiments
It appears that larvae sense food concentrations in the water, set their territory size accordingly, and vigorously defend it unless the energetic or social cost of fighting is greater than the food benefits received.
On the evolution of commensalism in the Chironomidae
Commensalism is widespread among the Chironomidae and association with large-sized hosts is thought to make the chironomid commensal less vulnerable to a variety of freshwater predators which are in general gape limited.
Observed frequency of phoresy in these streams were similar to published rates for chironomid/hellgrammite associations, and this is the first documentation of chironOMid phoreSy on hellgrammites in Maine.
Density and Dispersion in Laboratory Populations of Caddisfly Larvae (Cheumatopsyche, Hydropsychidae)
In nature and the laboratory, caddisfly larvae of the genus Cheumatopsyche display aggressive behavior and spacing. It was proposed that their dispersal and subsequent patterns of dispersion would be
