Chortoicetes terminifera is recorded for the first time as a host of Scelio parvicornis. Mean levels of parasitism ranged from 7.2‐20% of host egg pods. S. parvicornis overwinters as first‐instar larvae in diapause host eggs. Incubation experiments indicate that a facultative diapause, induced by low temperature occurred at the late first‐instar larval stage in 36.3% of the population.
