Food Plants of Geometridae with other Notes* 



By David Bruce, Brockport, N. Y. 



In the following list of food plants there is this distinction to be 

 made; ist, there are given the natural food plants of the larvae, that is, 

 the plants I have found the lar\3e feeding upon in a wild state, and 2nd, 

 there are given the plants I have fed to the lar\-iE raised from eggs laid by 

 captured females, which may or may not be the food plant in nature ; 

 these latter are marked "bred" in the list following, I may add that I 

 usually find the larvie of the GeometridiB are best dislodged from young 

 trees by a sudden smart blow with a heavy club. Sweeping with a net in 

 the evening is the way I have found best results with those species that 

 feed on low plants. I have followed Grote's Check List in names and 

 numbers. 



1. C. cicmataria. Double brooded ; fed in large numbers upon the 

 Elm, and raised in fine variety. Bred, (Pyrrhopappus, Clematis). 



2. C. transversata. Raised from larva; beaten from most forest trees, 

 though not from Oaks, which do not grow in my vicinity. (Clethra, 

 Myrica, Geranium. ) 



13. T. crocallata. One larva on Spice Bush. Bred. (Sumach, 

 Chestnut). 



18. M. inaJomaria. Found moth emerging from a pupa in a crevice 

 in bark of Cottonwood near Denver, Col. Very common in that locality 

 on trunks of Cottonwoods, and at light. 



23. C. confusaria. Larva swept from Wild Clover by roadside. 



27. E. alniaria. Bred from the t%^, and found many larvae on Elm. 

 The eggs are laid in a band, and look like a small tape worm. The pupa 

 is m a thin web in a leaf A large Elm in my door yard was full of the 

 larvae every year. (Universal feeder. ) 



28. E. subsignaria. Elm and Maple. (Feeds on all trees.) 



29. S. kentaria. This moth flies at the end of April and beginning 

 of May. The eggs are green, turning to reddish brown, hatching in 14 

 days. The larvae fed on Maple, and the moth emerged in July. It is 

 thus double brooded. Bred. I have beaten the larvae from Beech and 

 found one full fed on Basswood. (Birch.) 



31. A htibnerata. Raised from the egg on Maple. Bred. 



40. E. hilinearia. I found a larva on Choke Cherry near Denver, 

 Col, which produced this moth. I have not been successful with this 

 genus [Endropia). I have tried to rear many of the species from the 

 eggs, but the larvae would not feed. 



52. T. fervidaria. Larvae found on most forest trees, Beech, Birch, 

 Cherry, Elm, etc.
