Meeting Abstract 47.1  Saturday, Jan. 5  When is a wasp supercool? CORRIGAN, S.T.*; IRWIN , J.; Central Wash Univ corrigas@cwu.edu The summer biology of many temperate social Hymenoptera has been well studied, but little data are available concerning their winter physiology. To ascertain the lower limits to low temperature survival of vespid wasps, we measured the supercooling […]
