Nuptial gifts of male spiders function as sensory traps.
While nuptial food gifts come in various forms in arthropods, their evolutionary origins are unclear. A previous study on insects has shown that such gifts may arise as a sensory trap that exploits a female's underlying motivation to feed. Here I present independent evidence of a sensory trap in spiders. In certain visually oriented spiders, I suggest that males initially exploit the maternal c...

متن کاملNuptial gifts and the evolution of male body size.
In many insect systems, males donate nuptial gifts to insure an effective copulation or as a form of paternal investment. However, if gift magnitude is both body size-limited and positively related to fitness, then the opportunity exists for the gift to promote the evolution of large male size. In the striped ground cricket, Allonemobius socius, males transfer a body size-limited, somatic nupti...
متن کاملFemale bushcrickets fuel their metabolism with male nuptial gifts.
In many arthropods, such as bushcrickets, males donate protein-rich nuptial gifts-so-called spermatophores-to females, which females ingest while the sperm enter the female's reproductive tract. Previously, it was shown that females route spermatophore nutrients over the course of hours and days to egg production or body synthesis. We investigated whether female bushcrickets fuel their metaboli...
متن کاملMolecular dissection of nuptial gifts in divergent strains of Ostrinia moths: Nuptial gifts in Ostrinia moths
Seminal fluid proteins (SFPs) produced in the male accessory glands and ejaculatory duct are subject to strong sexual selection, often evolve rapidly and therefore may play a key role in reproductive isolation and species formation. However, little is known about reproductive proteins for species in which males transfer ejaculate to females using a spermatophore package. By combining RNA sequen...
