Melon Worm DiapUania Tiyalinata Linn This pest occurs in large numbers in Florida, Georgia and North Carolina. Description and Habits Parent Moths Melon worm moths are beautiful crea- tures, which may often be seen flying about cucurbit fields during the late fall months. They have wings of a pearly white color, bordered with brownish black (Fig. 1). The abdomen is also pearly white, tinged with brown at the caudal end, which terminates in a large movable brush of elongated yellow and dark-brown scales. Nearly all the underside of the body, including the legs, is of the same color as the wings. The wings expand one inch, or a little more. The moths, although shy and rapid fliers, are fre- quently seen during the daytime. Eggs These are pearly white in color, very small in size, and are laid in groups of from two to six or more on the stems, leaves and buds. They hatch in about four days in warm weather.. Lariae Just hatched larvae are about a twen- ty-fifth of an inch long, with a pale brown head, and body of a pale yellow color, with no distinct markings. At about three days of age the skin is molt- ed for the first time, and then the body shows two faint longitudinal sub-dorsal white stripes, which become more prom- inent as the larvae develop. By these two white stripes melon worms (Fig. 1) may be readily distinguished until they are nearly grown, when the white stripes dis- appear. These worms often feed for their en- tire lifetime on the foliage, remaining on the underside partially concealed by thin silken webs. They also feed in the terminal bud clusters, and bore into melons and squash like the pickle wo
