SLUG-CATERPILLARS.

A similar moth, the Euclea penulata Clem., is not uncom- 
mon in Minnesota. A single caterpillar, found also upon 
the cherry, was bred in captivity, and proved to be this in- 
sect. The moth has a dark brown body, and the green 
marks of the front-wings are narrow and of a brighter 
green than in chloris. It is shown in Fig. 94, Plate XXII. 
Still another moth is found from time to time near the 
electric light. It is Euclea cippus Cram. var. quercicola H.S. 
Its larva feeds upon apple, plum, cherry and some other 
plants, but isnot common. The moth is also dark brown; 
the large green band on the fore- wings is in this case simply 
indicated by a number of large and small green spots, the 
one nearest to the body being larger and of a triangular 
shape. Fig. 95, Plate XX, shows two slug-caterpillars. 
THE CHERRY SLUG-CATERPILLAR. 
(Adoneta spinuloides H.5S.). 
The slug-like caterpillars of this moth are very curious 
erass-green objects, which, with their flat bodies ornament- 
ed with a few reddish lines, almost look lke excrescences of 
the leaf. They move by a sliding and almost imperceptible 
motion. When mature they form very small and almost 
perfectly globuiar brown cocoons, fastened to leaves or 
twigs. In this condition: they remain until spring, when 
they transform to pupe and soon alterward to moths. 
(Fig.96, Plate XXII). These are distinguished by a uniform 
dark brown color, with irregular bands of whitish spots. 
The rather faleate fore-wings are edged with brown and 
white. This insect is also uncommon, still a single small 
cherry tree was found, upon which several hundreds of these 
caterpillars were feeding. A rapid increase of this insect is 
not likely to take place, as but few of the caterpillars 
escape parasitic insects. Among these is a rather large and 
peculiar fly, the Systropus macer Loew, which is apparently 
much more bulky than the insect in which it fed.
