Cognitive functioning is vital for enabling animals of all taxa to optimise their chances of survival and reproductive success. Learning and memory in particular are drivers of many evolutionary processes. The field of cognitive ecology explores how the environment can affect investment into cognitive capacity and learning ability. In this study, we examine how developmental plasticity can affect cognitive ability by exploring the role of early social environment on influencing problem solving ability and learning of female black field crickets, Teleogryllus commodus. We used two learning paradigms, an analog of the Morris water maze and a novel linear maze, to examine cognitive differences between individuals reared in two acoustic treatments: silence or calling. Although there was no evidence of learning or memory, individuals that took longer to mature solved the Morris water maze more quickly. This suggests that increased investment into cognitive development is likely associated with increased development time during immature stages. Inconsistent individual performance and motivation during the novel linear maze task highlights the difficulties of designing ecologically relevant learning tasks within a lab setting. The role of experimental design in understanding cognitive ability and learning in more natural circumstances is discussed.

Testes from nymphs of the last three instars of 10 populations of Australasian "black" field crickets, Teleogryllus commodus and T. oceanicus, and some of their hybrids, were examined to determine the number and morphology of their chromosomes. All populations gave counts of 2n = 27 in the male. The karyotypes of different populations and the hybrids are presented in tabular form with illustrations and idiograms. Some anomalies in chromosome numbers and structure were found, notably the occurrence of polyploid cells in the hybrids of T. commodus populations and in the interspecific hybrids.Chromosomal polymorphism was found to be common, except in some non-continental populations. Lampbrush-like chromosomes were found in metaphase 1 of interspecific hybrids and in the intraspecific hybrids of T. oceanicus. Achromatic gaps occur in T. oceanicus and in a population of T. commodus from Victoria, Australia.
