“…Dobsonflies have aquatic larvae and terrestrial pupae and adults (Cover and Bogan 2015). Larvae of some species are sensitive to pollution (Maki et al 1973; Tarter et al 2010) and good bio-indicators of freshwater ecosystem health (Nair et al 2015). The life cycle of most dobsonflies ranges from one to two years, though some species live up to five years (Bowles 1990; Cover and Resh 2008; Álvarez 2012; Cover and Bogan 2015).…”

The Megaloptera are an interesting, but relatively poorly studied group of insects. Among the new world Megaloptera, it is not known the effect of the neartic-neotropical transition zone on their biogeographic distribution. Here we present potential geographic distributions based on ecological niche models of the species of Megaloptera from North America that occurred in the transition zone. Results suggested that the geographic range of Corydalinae (dobsonflies) in the transition zone is associated to mountainous formations and that most species favour for warm climates with higher precipitation rates. Climate types tend to be important for species that show narrow geographic ranges, but precipitation tends to be the most important variable to explain species dispersion. In addition, Chauliodinae (fishflies) and Sialidae (alderflies) may have no relation with the transition zone. Overall, our models support the dispersion of dobsonflies from the neotropics to North America and explain the two endemisms in Mexico as the result of the formation of the transition zone.

ObjectiveFlathead Catfish Pylodictis olivaris are a widespread aquatic invasive species within the United States and a recent invader in the Susquehanna River basin, Pennsylvania. Flathead Catfish are piscivores known to consume native and recreationally important fish species. In the mid‐Atlantic United States, it is unknown how this invader is impacting food webs and which species may be at greatest predation risk. To address this knowledge gap, we DNA barcoded stomach contents collected from Flathead Catfish to identify prey species and elucidate potential predatory impacts of Flathead Catfish in the Susquehanna River.MethodsWe used a Bayesian hierarchical multivariate probit model to investigate if the probability of prey species occurrence in the diets of Flathead Catfish varied seasonally or was a function of Flathead Catfish length.ResultA total of 576 Flathead Catfish were collected during 2020–2021, with 241 individuals having recoverable stomach contents. In all, we identified 47 different prey species. The most common prey species were rusty crayfish Faxonius rusticus, Margined Madtom Noturus insignis, and shiners Notropis spp. While frequency of occurrence of prey species differed across Flathead Catfish length classes (<300 mm, 301–600 mm, 601–900 mm TL), rusty crayfish were commonly found (33.7–44.0% of diets) in stomachs of all size‐classes.ConclusionWe found that Flathead Catfish length and seasonality did influence occurrence probability differentially for several prey species. For example, Channel Catfish Ictalurus punctatus were more likely to appear in shorter Flathead Catfish while Smallmouth Bass Micropterus dolomieu appeared in larger Flathead Catfish. We demonstrate significant variation in Flathead Catfish predation, increasing our understanding of predator–prey dynamics, which is necessary to better manage and identify future impacts to aquatic communities in the Susquehanna River basin.

The dobsonflies (Megaloptera, Corydalidae) are an interesting group of insects, but among the New World dobsonflies, it is not known the effect of the Neartic-Neotropical transition zone on their biogeographic distribution. Here we studied at the species level, the records on the geographic range of the dobsonflies that occurred in and near the transition zone. We presented potential geographic distributions based on ecological niche models for several species of dobsonflies. Results suggested that the geographic range of dobsonflies in the transition zone is associated to mountainous formations and that most species favor warm climates with higher precipitation rates. Climate types tend to be important for species that show narrow geographic ranges, but precipitation tends to be the most important variable to explain species dispersion.Overall, our models support the dispersion of dobsonflies from the Neotropics to North America and explain the two endemic species in Mexico as the result of the formation of the transition zone.
