Reading edition
See an account of Mr. Gregson’s experiments on the Abraxus grossulariata, ‘Proc. Entomolog. Soc.,’ Jan. 6th, 1862: these experiments have been confirmed by Mr. Greening, in ‘Proc. of the Northern Entomolog. Soc.,’ July 28th, 1862. For the effects of food on caterpillars, see a curious account by M. Michely in ‘Bull. De La Soc. Imp. d’Acclimat.,’ tom. viii. p. 563. For analogous facts from Dahlbom on Hymenoptera, see Westwood’s ‘Modern Class. of Insects,’ vol. ii. p. 98. See also Dr. L. Moller ‘Die Abhängigkeit der Insecten,’ 1867, s. 70.
