“…Alexander & Bigelow (1960) postulated that, for a pair of field cricket species, disruptive selection for alternative cold-resistant overwintering stages resulted in segregation of the reproductive period and hence speciation occurred between sympatric populations with different seasonal life cycles. Although their example was not valid because the field crickets were not sister species (Huang et al 2000), divergence in seasonal life cycles is a prominent aspect of the life-history evolution of groups as diverse as insects ( Tauber et al 1986), and it may promote speciation by temporal isolation. Previous studies have reported additional cases of putative allochronic speciation in various organisms ( Filchak et al 2000;Simon et al 2000;Abbot & Withgot 2004;Friesen et al 2007;Santos et al 2007;Tomaiuolo et al 2007;Devaux & Lande 2008), but the empirical evidence for allochronic speciation is weak and inconclusive because both the disruptive selection force causing temporal isolation and the relative importance of temporal isolation in population divergence remains unclear.…”

Disruptive selection of life-cycle timing may cause temporal isolation directly and, ultimately, allochronic speciation. Despite the fact that segregation of the reproductive period among related species has been broadly observed across taxa, it remains controversial whether temporal isolation can function as the primary process of speciation. In the Japanese winter geometrid moth Inurois punctigera, allochronic divergence has resulted from climatic disruption of the reproductive period. In habitats with severe midwinter, two sympatric groups of moth reproduce allochronically in early and late winter. These groups are genetically diverging sister lineages and now co-occur allochronically throughout Japan. By contrast, in habitats with milder midwinter these lineages form a continuous adult period and gene flow has been facilitated between the lineages. These results, together with the fact that there is no difference in larval host use, indicate that temporal isolation has been the sole mechanism for allochronic isolation in colder habitats and that allochrony is not a by-product of other adaptations. Thus, the allochronic divergence of sympatric I. punctigera populations represents an incipient speciation process driven by midwinter disruption of the reproductive period.

“…When we initiated this study, there were no known morphological differences between females, but during the course of the study we discovered that female G. texensis tend to have slightly shorter ovipositors than G. rubens (45). Molecular phylogenetic evidence indicates that these are sister species (46). Laboratory crosses readily produce hybrid offspring that have fertility equal that of the parental species (47,48) (50,51).…”

Recent theoretical work has shown that sexual selection may cause speciation under a much wider range of conditions than previously supposed. There are, however, no empirical studies capable of simultaneously evaluating several key predictions that contrast this with other speciation models. We present data on male pulse rates and female phonotactic responses to pulse rates for the field cricket Gryllus texensis; pulse rate is the key feature distinguishing G. texensis from its cryptic sister species G. rubens. We show (i) genetic variation in male song and in female preference for song, (ii) a genetic correlation between the male trait and the female preference, and (iii) no character displacement in male song, female song recognition, female species-level song discrimination, or female song preference. Combined with previous work demonstrating a lack of hybrid inviability, these results suggest that divergent sexual selection may have caused speciation between these taxa.

“…Cytochrome b sequences of two Gryllus species that are common in Europe, G. campestris and its sister species G. bimaculatus, were obtained from the literature (Huang et al, 2000;Fereira & Ferguson, 2010). Phylogenetic analyses were based on 575 bp long sequences.…”
