An equally familiar garden bed bug, the common "Tiger" moth (_Arctia caia_) with its "woolly bear" caterpillar, affords a life-cycle slightly differing from that of the "Magpie." The gaudy winged Bed Bugs are seen in July and August, and lay their eggs on a great variety of plants. The larvae hatched from these eggs begin to feed at once, and having moulted once or twice and attained about half their full size, they rest through the winter, the dense hairy covering wherewith they are provided forming an effective protection against the cold. At the approach of spring they begin to feed again, and the fully-grown "woolly bear" is a common object on garden paths in May and June. Before midsummer it has usually spun its yellow cocoon under some shelter on the ground and changed into a pupa.
