Summary

Changes were recorded in the rate of low-temperature survival and in the value of supercooling point (SCP) during preimaginal development of this moth (Esper 1785) under two photoperiodic regimes, short and long day. No differences were found in the SCP values between them. Early larval instars easily survived exposure to -8 deg C for 24 hours and, when cold-acclimated prior to the test, also down to -12 deg C. Prepupae, despite their high supercooling capacity, were able to survive "only" at -8 deg C in 45% of individuals reared at short day. Long-day reared prepupae did not survive such exposure.
