As soon as such symptoms are noted, a physician should be summoned or the victim taken to a hospital. Treatment consists of frequent, small, hypodermic injections of epinephrine in the ratio of one part of epinephrine to 1,000 parts of water. Dr. W. Ray Jones[7], who developed and perfected this treatment, reports that it is immediately effective and recommends that all commercial beekeepers provide themselves with hypodermic kits and a small supply of epinephrine. Even persons who are apparently immune to bee-sting venom through having received bee stings during the course of many years of work in the apiary, may suddenly develop supersensitivity. The treatment is relatively simple, may be self-administered, and has already proved effective in treating serious cases of excessive susceptibility resulting from supersensitive persons receiving bee stings. Experimental use of calcium lactate to counteract “sting shock” indicates a high degree of success. Physicians should investigate “Death by Sting Shock,” p 234, _Science News Letter_, April 9, 1955. Use of antihistamines or a hormone of the cortizone family has had some success. Puss Caterpillar (_Megalopyge opercularis_) Superficially resembling a tiny, light, golden-yellow kitten, the puss caterpillar is a short, bushy larva of a small gray-brown moth with whitish underwings. When disturbed, the caterpillar rears back on its hind legs and “makes a face.” The species has long been widespread throughout the southern states feeding on the foliage of oak, elm, plum, and sycamore trees. They have been found also in truck gardens and orchards. Recently they have invaded the desert mountains of the Southwest, having been reported by Stahnke as especially numerous in the Globe-Miami area of Arizona, feeding on the foliage of oaks. [Illustration: _Puss caterpillar_ (Courtesy Dr. Herbert L. Stahnke)] Because of their long, silky hairs, children are tempted to touch them. Under the hairs are small protrusions, each bearing a circlet of very small spines resembling tiny porcupine quills. The venom is injected when these spines pierce the child’s skin and the tips break off, producing a burning, itching, irritated, inflamed area. The welts, ranging in size from a dime to a dollar, are sometimes followed by severe muscle cramps and headache. Not lethal, the toxin may cause enough sleeplessness in a child to reduce his resistance to other infections.
