House Cricket. 

 (Gryllus domesticus Linn) 



These insects are quite common and at times do considerable 

 damage to clothing. They often damage clothes hung in a dark 

 and damp closet or clothespress; also hiding in fireplaces, pantries 

 and baseboards. The house cricket shows a special fondness for 

 liquids such as milk, and may be found in the milk pans if left 

 uncovered. The crickets vary from brown to black according to 

 the species. The head has two very long antennae, the hind legs are 

 large and strongly developed for jumping. The chirping is done 

 entirely by the male by elevating the outer wings or tegminae, and 

 then scraping them together, one over the other, thus producing a 

 vibration. It is supposed to be a call from the male to the female.
