Quick Summary

A spermatophore is a capsule or packet containing spermatozoa, extruded by the male of certain animals like insects and arachnids. This packet is then transferred to the female's reproductive tract for fertilization.1

In some species, such as scorpions and spiders, the male deposits spermatophores that are anchored to the ground or transferred via specialized appendages. For insects, spermatophores are often deposited in the female's vagina, where their walls break down, allowing the sperm to reach the seminal receptacle. In many orthopterans (grasshoppers, crickets, and katydids), the spermatophore is formed during copulation and contains sperm and fluid, serving as a direct medium for sperm transfer. This method is particularly important for species that haven't developed direct copulatory organs, as the spermatophore protects the sperm from drying out.234
