A New Species

A new species of Oecanthus is described from extreme northeast California. Oecanthus salviisp. nov. is currently known only from Lake Annie in Modoc County, California, and occurs on sagebrush (Artemisia) and rabbitbrush (Ericameria). It has the narrow tegmina, antennal markings, metanotal gland configuration, and trilling song found in the Oecanthus nigricornis species group. Song details and morphology, including the shape of the subgenital plate and copulatory blades, are provided in this paper. This new species has been given the common name of sage tree cricket.

Multiple Male

Female choice based on multiple male traits has been documented in many species but the functions of such multiple traits are still under debate. The satin bowerbird has a polygynous mating system in which males attract females to bowers for mating; females choose mates based on multiple aspects of males and their bowers. In this paper, we demonstrate that females use some cues to decide which males to examine closely and other cues to decide which males to mate with. Female visitation rates to bowers were significantly related to male size and the males' ‘solitary’ display rates, and, to a lesser extent, to the numbers of bower decorations. After controlling for female visitation rates, it was found that a male's mating success was significantly related to his size and the rate at which he ‘painted’ his bower with saliva and chewed up plant material.

AbstractConsidering the advertisement call in anuran as a sexually selected trait, we investigated the effects of male call parameters on reproductive success in midwife toad Alytes obstetricans. The pattern of advertisement call was studied in 81 males. The mean fundamental frequency varied among males. Fundamental frequency, call duration and male size correlated with the male mating success. From the stepwise regression analysis, the low call frequency was found to influence significantly the number of carried eggs and the hatching success. The fact that a single male may fertilise the eggs of several females and a single female may mate with several males constitutes an original sexual system. Large males obtained more matings and showed a higher hatching success. Female choice for dominant frequency may be regarded as a related-fitness trait being correlated with male size. Anyway, the male size and the female choice for low calls result in a same evolutionary trend favouring a best fitness.

Opportunistic Feeding

Intruding Oecanthus nigricornis (Walker) females stole nutritional glandular secretions from males engaged in post-copulatory behavior with their mates. This mating strategy may enhance female reproduction.Mating behavior of Oecanthus spp. begins with elaborate male courtship involving vibratory, acoustic, and olfactory signalling. The female mounts the male, with copulation occurring soon after. During courtship and after copulation the female remains mounted and is provided with male metanotal glandular secretions. These nutritional secretions and the consumed spermatophore increase reproduction (Bell 1979; in press).

First Time

AbstractBlack horned tree crickets, Oecanthus nigricornis (Walker), were continuously reared for the first time in the laboratory. Optimum rearing conditions per unit effort involved 2 months at −5 °C to terminate egg diapause, and subsequent incubation of eggs from infested raspberry cane segments at 27 °C and 45% relative humidity. Eggs began hatching in 2 weeks, and second generation eggs were obtained within 2.5 months. The best survival from egg to adult was 55%. The possibility that male tree crickets provide a nutritional investment in their progeny is discussed.

Vibratory Signals

Adult male tree crickets, Oecanthus nigricornis (Walker), employ acoustic, olfactory, and vibratory signals during mating. Females were attracted significantly (p < 0.001) to the conspecific courtship song and to conspecific male scent. Males had 63, 39, and 0% copulation success in normal, waxed-over metanotal gland, and nonsinger groups respectively. Males provide the females with metanotal glandular products and a subsequently ingested spermatophore. Females appear to select mates on the males' ability to communicate these nutritional investment capabilities.
