The spermatophore transferred by the male decorated cricket Gryllodes supplicans to the female during copulation includes a large gelatinous portion (spermatophylax), which the female removes and feeds on immediately after mating. Females usually removed and ate the smaller sperm-containing portion (ampulla) within 1 to 7 minutes after fully consuming or losing the spermatophylax. Complete sperm transfer requires that the ampulla remain attached for a minimum of 50 minutes; this corresponds to… Expand
SPERM COMPETITION AND THE EVOLUTION OF NUPTIAL FEEDING BEHAVIOR IN THE CRICKET, GRYLLODES SUPPLICANS (WALKER)

  • Evolution; international journal of organic evolution
  • 1986
TLDR
The pattern of sperm predominance in doubly mated female crickets, Gryllodes supplicans, was investigated using a radiation‐sterility technique; evidently, mixing of ejaculates within a female's spermatheca does occur. Expand
COURTSHIP FEEDING AND THE FITNESS OF FEMALE KATYDIDS (ORTHOPTERA: TETTIGONIIDAE)
  • D. Gwynne
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1988
TLDR
Katydid males (Requena verticalis) produce spermatophores with a large sperm‐free sperMatophylax, which is eaten by the female after mating, and this male‐produced food substitute for other food in the diet of the female or is it a source of specialized nutrients. Expand
Effect of nuptial feeding on the mating behaviour of female ground crickets
Female striped ground crickets, Allonemobius fasciatus, feed on male tibial glands while in copula. This behaviour has been interpreted as nuptial feeding and a method by which copula duration isExpand
Fluctuating asymmetry and sperm transfer in male decorated field crickets (Gryllodes sigillatus)
TLDR
The results imply that developmental instability affects both gamete production and mating decisions among males, although the relationships between spermatophore size, sperm number and asymmetry in females are unlikely to be the result of males perceiving differences in female FA. Expand
Female choice in the field cricket Gryllus bimaculatus (De Geer)
TLDR
This study shows that multiple mating is a potential mechanism of mate choice and a function of multiple mating may be to dilute the sperm stored from previous matings with that of the current male, so increasing his representation in offspring production. Expand
Male crickets increase sperm number in relation to competition and female size
Abstract There is evidence to suggest that males of various species can respond to the threat of sperm competition by varying the amount of sperm transferred during copulation. We tested this in twoExpand
INGESTION OF MALE HEMOLYMPH BY FEMALE
Male sagebrush crickets, Cyphoderris strepitans, offer an unusual nuptial food gift to females during copulation: females are permitted to feed on the hind wings of males and ingest hemolymph thatExpand
SPERM COMPETITION IN THE FIELD CRICKET GRYLLUS INTEGER (ORTHOPTERA: GRYLLIDAE)
TLDR
Considering all egg dishes, NN and RN females produced significantly more offspring than NR, but there were no differences in the percentage of eggs hatching when different dishes were compared. Expand
Male bushcrickets tailor spermatophores in relation to their remating intervals
TLDR
It is argued that variation in spermatophore size represents a trade-off between the number of matings a male can perform and the magnitude of their investment in each female, and males provide small sperMatophores when their potential mating rate is high but invest parentally in fewer females when mating potential is low. Expand
Hydration benefits to courtship feeding in crickets
TLDR
Data suggest that female G. sigillatus accrue fitness benefits by consuming spermatophylaxes when alternative sources of water are unavailable, and females appear to allocate water contained in sperMatophylAXes towards reproduction as opposed to survival. Expand

Mating behavior of Nemobiine Crickets--Hygronemobius, Nemobius, and Pteronemobius (Orthoptera: Gryllidae)
TLDR
Mating in Hygronemobius alleni is no more complex than in most other gryllids: courtship is brief, a full-sized sperMatophore is passed during the first mounting, and behavior after spermatophore tube insertion involves no mouthing of special glandular areas and no continued coupling. Expand
Sexual Selection and Paternal Investment in Insects
TLDR
It is hypothesize that female preference for greater male parental investment may have been the selective context for the evolution of all types of male investment patterns in insects. Expand
Calling display and mating behaviour of Copiphora rhinoceros Pictet (Orthoptera: Tettigoniidae)
TLDR
Males of a neotropical katydid, Copiphora rhinoceros, were found to alternate stereotyped bouts of body vibration (tremulation) with an 8.7-kHz air-borne song, which is remarkable in combining vegetation-conducted transverse waves with stridulation. Expand
Female mating frequency and progeny production in singly and doubly mated house and field crickets
TLDR
Nymph production increased significantly with the time the spermatophore was attached in singly mated A. domesticus and G. integer, andRemating by female crickets partly functions in offsetting the probability of a failed initial mating. Expand
