Geometrid Moth

Geometrid Moth

Common Name: Geometrid Moth

Order Name: Lepidoptera

Family Name: Geometridae

Most moths have bilateral symmetry but this large group of moths know as Geometrids are striking for the variety of “zigzag” markings and wings with serrated edges. At rest, this group holds its wings in a flat plane, perpendicular to their body. Caterpillars of this group lack legs in the center portion of their long, tubular bodies. Having two or three pair of clasping prolegs at the back and three pair of thoracic prolegs legs up front, they have adopted a looping form of locomotion. When disturbed, the caterpillars mimic a branching twig by holding on with their prolegs and stretching themselves erect and holding perfectly still. They can often be seen suspended below their food plant by a silken thread.
