In Orchesella cincta males, spermatophore deposition occurs typi- 
cally only in the first half of the reproductive instar (Joosse, Brug- 
man and Veld, 1973). The maximum number of males of Sinella 
coeca exhibit spontaneous spermatophore deposition in the first half 
of the instar. If reproduction in S. coeca females resembles that in 
S. curviseta and synchronization of molting occurs, S. coeca females 
probably have access to an abundance of spermatophores.
