Looper Moths - Family Geometridae

This page contains pictures and information about Moths and Caterpillars in family Geometridae that we found in the Brisbane area, Queensland, Australia.
Looper Caterpillar 
Most of the Caterpillars in family Geometridae have one or two pair of prolegs. The caterpillars move with curving their bodies into loops. This is why they commonly called Loopers. They are also known as Inch Worms because they apparently measuring off one inch at a time as they move. Some of them are called Twig Caterpillars because their resting posture look like a twig.

The Geometridae caterpillars are usually hairless and with slender body. They are well camouflaged in green or brown in colour. Most of them feed on leaf and active during the day.
Most of them are easy to rear. The GEOMETRIDAE usually pupate in plant materials or in soil with a flimsy cocoon.

Adult moths are medium to large size. Most of the them have camouflaged wing patterns. These patterns are usually wavy lines extend across both fore and hind wings. These moths rest with a standard posture, holding wings outspread and tightly pressed against the surface on which they are sitting, with the antenna held under forewing. This eliminates the shadow as well as the wings outline for a better camouflaged posture. Most Geometridae moths are active at night. They are not the strong fliers.
Eggs are nearly always of the flat type, although some are upright. They may be lay singly, in pair or in groups.    
Geometridae is a large family. We found many of them in Brisbane and listed as follow.  

Subfamily Ennominae - Twig Caterpillars

ENNOMINAE - Most Caterpillars in this subfamily are resemblance to dead twigs or other parts of their food plants. The adult moths are active at night. Most of them are grey or dark brown in colours.

GEOMETRINAE - The mature caterpillars in this subfamily only have one pair of ventral prolegs. They can move only in the looper fashion. Adults fly weakly at night. Some are green in colour hence the common name Emeralds.
