Summary

Overwintering larvae of the cranefly Tipula paludosa from an upland grassland in northern England were freeze tolerant with 94% survival of freezing in samples cooled at 0.1 deg C/min. Traces of six polyhydroxy compounds were detected by gas chromatography of larval extracts and haemolymph. Total lipid content was 1.22 mg/100 mg body weight, and total protein was estimated at 19.9 mg/100 ml body water. These findings are compared with the few available data for the Tipulidae in relation to their cold survival in upland habitats.
