May. The moths of this family are frequently very 
injurious to useful plants and are readily recognized by 
their wasp-like appearance, quick movements, and by the 
brush-like arrangement at the tip of the body. The 
moth is nearly one-half an inch long, color deep blue, 
having three yellow bands across the abdomen, a yellow 
collar, and yellow and blue markings on the eyes. It 
flies rapidly, in the hottest sun, but is easily captured. 
The females deposit their eggs near a bud of the current 
season’s growth, and preferably on the outer branches. 
The larva, as soon as hatched, eats its way to the center of 
the stem, where it remains until the following summer, 
when the moths again appear, to repeat the work of 
destruction. 
Remedies —The presence of the larva may be known by 
the sickly color of the leaves and the smallness of the 
fruit. The only practical remedy known, is to prune off 
and burn the affected branches in early spring. The 
pruning will also serve an additional purpose in assuring 
larger and better fruit. 
the garden web worm (Eurycreon rantalis). 
The most remarkable insect visitation of the year to 
Colorado was the presence of this insect. The moths 
appeared in immense numbers late in April, covering the 
plains and reaching well up into the mountains, and em¬ 
bracing the greater portion of the State. The larva was 
first described by Dr. Riley in 1873, prior to which 
time it was unknown. 
It is a widespread and very variable species, extending 
throughout the United States. The general color of the 
moth is a light or dark grav, marked by two irregular 
transverse pale lines, and a dark reniform spot on the 
discal cell. The perfect insect, larva and pupa, are accu¬ 
rately figured by Dr. Riley in the report of the Depart¬ 
ment of Agriculture for 1885. The larva fed upon a 
great range of plants—its favorite native food plants be-
