FAMILY GEOMETRID2E. 

 ("Loopers.") 



Tlie name is given because of the looping or 

 '' measuring" movements of the caterpillar. Tiie 

 adults are small to medium size, with colours 

 ranging from dark brown, grey, to pale green. The 

 Avings are often marbled, and this blends in most 

 markedly with the medium on which the flat wings 

 of these moths rest. It is hard to detect these 

 moths on posts or walls. 



The larva advances by looping movements. The 

 head is thrust forward, and tlic I'cmainder of the 

 body is looped up, bringing the tail near to the 

 head; then the liead is puslied forward again. 

 This is necessary because there are only two pairs 

 of fleshy legs instead of four. Tliese larvaB also 

 exhibit great muscular control; tliey stretch them- 

 selves and remain rigid, i*esembling either brown 

 or green twigs. Tliey can be captured by shakinsj 

 a branch over an open umbrella.
