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).

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.

Copulatory Position

The courtship, copulation and post-copulatory behavior, as well as acoustic communication of the Neotropical cricket Endecous (Notendecous) onthophagus is described under laboratory conditions and compared with other phalangopsids whose mating system was studied so far. We found that E. onthophagus present predictable mating sequences including seven events: (1) prolonged courtship; (2) male spermatophore extrusion during courtship; (3) female-above copulatory position; (4) prolonged copulation; (5) male forewings flipped over his head, exposing metanotal region along copulation; (6) copulation without spermatophore transfer; and (7) absence of guarding behavior. We suggest these events (1 to 7) as a behavioral line shared by phalangopsids, and we highlight variations that reflect the behavioral diversity of these crickets. The males of E. onthophagus produce the calling song (chirps) to attract females to mate, and also stridulates intermittently during the entire courtship period with distinct acoustic parameters during the stages of pre- and post-spermatophore extrusion.

Determining Factor

The Persian boxer mantid, Holaptilon brevipugilis, is the mantid most recently described from Iran. Here, I present some aspects of the courtship display and mating behavior of this species. I conducted 28 mating trials, quantified the relative frequency of all mating behaviors, and estimated the pre-copulation, copulation, and post-copulation periods. I also compared the effects of frontal vs. lateral approaches of the male for mating success, since frontal approach increases the risk that the male will be seen and cannibalized by the female. In 64% of trials, the male approached the female immediately, regardless of whether the female could see him or not. Copulation was successful in 61% of trials. Male courtship consisted of dorsoventral bending of the male’s abdomen and occurred in 10% of all trials, but only when the female was facing the male. In contrast, trembling of the forelimbs was not associated with copulation, occurred in 10% of all trials, and was always followed by the male moving away from the female. I observed one female cannibalizing a male post-copulation. The Persian boxer mantid might be sexually cannibalistic, but confirming this hypothesis would require further studies, including a focus on female hunger level as a determining factor in sexual cannibalism and in male courtship behaviors.

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.
