Increasing evidence suggests that key fitness-related behaviours of animals related to courtship and mating may be disrupted by anthropogenic stressors, including artificial light at night (i.e. light produced from anthropogenic sources). Despite its ubiquity in urban habitats, we currently know very little about how artificial night lighting affects the reproductive behaviours of most animals. Our study examined the effects of chronic (lifetime) exposure to one of four ecologically relevant intensities of artificial light at night (0, 1, 10 or 100 lx at night) on courtship and mating behaviours and acoustic sexual signalling in a common nocturnal and crepuscular insect, the Australian black field cricket, Teleogryllus commodus. We found that lifetime exposure to brighter (10e100 lx) artificial light at night affected some aspects of courtship and mating behaviour: it influenced mate choice and mating efficiency in a sex-specific manner, but did not affect the multivariate structure of male courtship calls. Our results suggest that chronic exposure to bright light at night may affect some aspects of mate choice and reproductive behaviour in this common insect, and warrants further study across taxa.

The genus Gryllus includes 82 described species that occur in America from Canada to Argentina as well as in several areas of Africa, Europe and Asia. There are 12 species in South America, which were described in the nineteenth century based on a small number of samples and inconsistent characters such as body coloration and external morphology. The aim of this article is to redescribe Gryllus argentinus Saussure, 1874 collected in the urban areas of Pelotas, Capão do Leão and Rio Grande, in the state of Rio Grande do Sul, southern Brazil, highlighting phallic sclerites, calling song and body morphometry. We designate the lectotype male, provide a combination of diagnostic characteristics and discuss the taxonomic situation of South American Gryllus species.

Study of the insect neuromuscular system appears very promising as a means of
explaining behaviour in terms of cellular operation. The relatively small number of
neurons, the ganglionic nature of the nervous system, the simplicity of the neuro-
muscular arrangement, and the repetitiveness of behavioural sequences all lend them-
selves to a solution of this problem. As a result, an increasing number of investigators
have been turning their attention to insects and especially to the large orthopterans.
Recently, Ewing & Hoyle (1965) and Huber (1965) reported on muscle activity
underlying sound production in crickets. The acoustic behaviour is well understood
(Alexander, 1961) and in the genera Gryllus, Acheta and Gryllodes communication is
mediated by three basic songs composed of three types of pulses. While working
independently on this system at the University of Cologne (W.K.) and the University
of Michigan (D.B.) using various Gryllus species, we found a number of basic
differences between the muscle activity in our crickets and that reported by Ewing
& Hoyle (1965) for Acheta domesticus. These two genera, Gryllus and Acheta, are so
nearly identical that they are distinguished solely by differences in the male genitalia
(Chopard, 1961). The present paper constitutes a survey of muscle activity patterns
producing stridulation in four species of field crickets. Since the work of the two
authors was carried out independently, non-overlapping experiments will be initialled
to indicate the investigator.
