Sequence Capture Phylogenomics of True Spiders Reveals Convergent Evolution of Respiratory Systems

open access: yesSystematic Biology, 2020
Abstract The common ancestor of spiders likely used silk to line burrows or make simple webs, with specialized spinning organs and aerial webs originating with the evolution of the megadiverse “true spiders” (Araneomorphae). The base of the araneomorph tree also concentrates the greatest number of changes in respiratory structures, a ...

Larvae of pyrrhocorid true bugs are not to spiders’ taste: putative Müllerian mimicry

open access: yesBiological Journal of the Linnean Society, 2019
Abstract Adults and larvae of a true bug, Scantius aegyptius (Heteroptera: Pyrrhocoridae), closely resemble sympatric firebugs, Pyrrhocoris apterus, and probably form a mimetic relationship with the latter species. Scantius aegyptius adults, although producing a secretion atypical of true bugs, are to some extent chemically protected ...

open access: yesScientific Reports, 2015
AbstractTrue predators are characterised by capturing a number of prey items during their lifetime and by being generalists. Some true predators are facultative specialists, but very few species are stenophagous specialists that catch only a few closely related prey types.
