A JAPANESE TACHINID PARASITE OF THE ORIENTAL MOTH, 
CNIDOCAMPA FLAVESCENS 
By John N. Summers, Melrose Highlands , Mass. 
The Oriental moth, a native of Japan, was accidentally imported and 
became established in the Dorchester section of Boston some time 
prior to 1906, as it was discovered there in numbers early that year. 
Very little has been heard of it since until last year when it was found 
to be quite abundant in some portions of the infested area. This year 
it was also quite abundant and a scout of neighboring sections showed 
that there had been considerable spread since the last survey was made. 
Last summer while in Japan studying natural control of the gipsy 
moth, my attention was called by Mr. J. L. King of the Japanese beetle 
laboratory at Yokohama to a Tachinid parasite of the Oriental moth 
which appeared to be quite effective in keeping it in check. A number 
of the adult Tachinids were reared and on my return to this country 
were sent to Dr. Aldrich for determination. He reported that they 
were specimens of Chaetexorista fl'avana B. & B. and that there were 
specimens at the museum from Japan which had been bred from the 
same host. 
This Tachinid passes the winter as a puparium inside of the host co¬ 
coon with the remains of the host larva more or less surrounding it. 
The adults began to issue this year about the middle of June and con¬ 
tinued to do so for nearly a month, moths and parasites coming out at
