ADVERSE TO SUNLIGHT.
Insects are often very susceptible to ultra-violet (which is, of course, a component of sunlight), as experiments by L. Raybaud have recently shown this fact explaining the aversion of some species to strong sunlight. In the rays from a mercuryvapor lamp, such creatures as snails, houseflies, and tadpoles, soon become torpid, and in the course of a few hours were quit© dead. Young grasshoppers perished in about two days. Adult grasshoppers showed no apparent injury after a week’s exposure, and spiders and beetles were unaffected.
