CATTLE GRUBS ( Hynoderma bo vis DeG. and H. lineatum DeVill. ) 
Ohio F. C. Bishopp (May 27): Apparently annoyance from the oviposition 
of the cattle bot flies has not been very great to date,, Cattle 
have been attacked on warm days but the actions indicate that the 
agitation of the- stock is mostly due to E, li neatum . 
On May 1 apparently all H. lineatum larvae had left the cattleJs 
backs. On May 27 a considerable number of H. bovi s larvae were still 
present in the backs of the cattle. The number ranged from to 15 
per animal. 
There is some difference of opinion as to comparative number of 
grubs in the backs of cattle in Ohio this year as compared with the 
.average. Most agree that the number is less than last year, which 
was an exceedingly bad year for them.
