	abstract = {<p>Anthropogenic factors, such as artificial light at night (ALAN), are increasingly linked to significant modifications in animal behaviours, such as foraging or migration. However, few studies have investigated directly whether the presence of ALAN affects the ability to find a mate (mate location). One direct effect of the presence of ALAN is that it can create a light barrier in an otherwise dark environment. This may have significant behavioural implications for nocturnally active species if it affects their ability to respond to potential mates. Our study, using the acoustically orienting Australian black field cricket, Teleogryllus commodus, determined experimentally whether the presence of a fragmented light environment influenced movement patterns of virgin females and males. Moreover, given the importance of male song for reproductive outcomes in this species, we assessed simultaneously whether such behaviours were modified by the presence of a male attraction call. We found that while initiation of movement was slower in the presence of ALAN, the behavioural shifts associated with its presence were relatively small compared to the influence of a broadcast male attraction call. The response to the male attraction call was typically stronger for females than for males, but both males and females modified aspects of behaviour when it was present regardless of whether their immediate environment was fragmented by artificial light at night or not. Artificial light at night may alter subtle aspects of movement and mating behaviour in this species, but ultimately does not provide a barrier to movement or mate location.</p>

	abstract = {<p>Ancylecha fenestrata is a rather large phaneropterine tettigoniid from Malaysia with leaf-like tegmina that are characterized by two crescent-like markings. This species is often raised in captivity, but publications about its biology are rare. Searching the internet we found several plants accepted for oviposition, but not for feeding. These plants have relatively fl eshy and leathery leaves and contain various substances (e. g. saponins, oxalic acid, speci fi c glucosides etc.) often harmful at least to verte- brates. Only a few plants appear to be used for both, egg deposition and feeding. Whether this is a strategy pursued by A. fenestrata in the wild, is unkown. Females oserved by us inserted up to 13 large kidney-shaped eggs (per leaf) in the leaf parenchyma of the Spotted Dracaena Dracaena surculosa often used for breeding. The chorion of the egg is composed of a thin, delicate outer layer that apparently forms a close association with the walls of the parenchyma cells of the leaf, followed by a broader spongy layer, a relatively thick and solid layer with dilatations (air spaces) connected by fi ne pore canals that also open out in the large spaces of the spongy layer, and a very thin basal layer. At temperatures of 22 to 25 \&deg;C and relatively high humidities, nymphs hatch within 70 days on average. The fi rst nym- phal instars are strikingly multicoloured. In the resting position, in which the forelegs are extended forwards, the hind legs backwards, and the long antennae are hidden under the abdomen, they resem- ble spiders. Males and females of A. fenestrata produce sounds by tegminal stridulation. Stridulatory organs are sexually dimorphic. As typical for many tettigoniids, males possess a strongly sclerotized fi le with \&ldquo;teeth\&rdquo; ( pars stridens ) on the underside of the left tegmen base and on the upper surface a scraper ( plectrum ) near to the so-called mirror. Females lack a mirror possessing several small fi les with laterally cuspidate teeth on the upper surface of the right tegmen, whereas the underside of the left tegmen is not conspicuously modi fi ed. When disturbed, both sexes produce alarm or defence sounds.</p>
