“…Light flashes can be used to communicate between conspecifics or to confuse predators, as in the Lepidoptera Nymphalidae Morphinae or in other insects with metallic, structural colors [27][28][29] . Several insects are known to produce light flashes when flying, as sexual signals: some Acrididae 19 ; damselflies of the family Chlorocyphidae Cowley, 1937, that have dark wings with several hyaline 'windows'; Ithomiini nymphalid butterflies with transparent wings; males of the calliphorid fly Lucilia sericata (Meigen, 1826) 5 ; or males (but not females) of the asilid flies Ommatius spp., with broadened and transverse 'corrugated' cell r1 30,31 (Fig. 2e).…”

Sound vs. light: wing-based communication in Carboniferous insects

et al. 2021

Acoustic communication is well-known in insects since the Mesozoic, but earlier evidence of this behavior is rare. Titanoptera, an ‘orthopteroid’ Permian-Triassic order, is one of the few candidates for Paleozoic intersex calling interactions: some specimens had highly specialized broadened zones on the forewings, which are currently considered—despite inconclusive evidence—as ‘resonators’ of a stridulatory apparatus. Here we argue that the stridulatory apparatus hypothesis is unlikely because the Titanoptera lack a stridulatory file on their bodies, legs or wings. Instead, comparing these broadened zones with similar structures in extant locusts, flies, and fossil damselflies, we find evidence that the Titanoptera used their wings to produce flashes of light and/or crepitated sounds. Moreover, we describe the first Carboniferous (~310 Mya) Titanoptera, which exhibits such specialized zones, thus corresponding to the oldest record of wing communication in insects. Whether these communication systems were used to attract sexual partners and/or escape predators remain to be demonstrated.

In this work, four new species of Ommatius are described from Peru; Ommatius amaru sp. nov. from Cuzco, Ommatius kuntur sp. nov. from Ayacucho and Cuzco, Ommatius uturuncu sp. nov. from Ayacucho and Pasco, and Ommatius yanantin sp. nov. from Cajamarca. All belong to the ampliatus species group, which is part of the holosericeus complex. Illustrations of external morphology, as well as dissected terminalia, are provided. A taxonomic discussion is given for all new species. A distribution map for the Peruvian species in the ampliatus group and an updated key to all species in this group are also given. The new species are named as a tribute to the Andean cosmovision which is based on thousands of years of pre-Columbian culture.
