  Note:  The  sheep  gadfly  ({Oestrus  ovis})  deposits  its  young  in 
  the  nostrils  of  sheep,  and  the  larv[ae]  develop  in  the 
  frontal  sinuses.  The  common  species  which  infests 
  cattle  ({Hypoderma  bovis})  deposits  its  eggs  upon  or  in 
  the  skin  where  the  larv[ae]  or  bots  live  and  produce 
  sores  called  wormels  The  gadflies  of  the  horse  produce 
  the  intestinal  parasites  called  bots.  See  {Botfly},  and 
  {Bots}.  The  true  horseflies  are  often  erroneously 
  called  gadflies,  and  the  true  gadflies  are  sometimes 
  incorrectly  called  breeze  flies.
