Considerations on an autumn record of Lestes larvae in Italy (Zygoptera: Lestidae)

– Autumn findings of Lestes larvae in a freshwater pool in Apulia, southern Italy are reported and discussed. Since all European members of this genus have a long embryonal diapause, lasting from the end of the summer to the following spring, it is tentatively concluded that this unusual occurrence is due to premature hatching, and that diapause was affected by temperature and by immersion.
