Damage:

Cabbage loopers are leaf feeders, and in the first three instars they confine their feeding to the lower leaf surface, leaving the upper surface intact. The fourth and fifth instars chew large holes, and usually do not feed at the leaf margin. In the case of cabbage, however, they feed not only on the wrapper leaves, but also may bore into the developing head. Larvae consume three times their weight in plant material daily (McEwen and Hervey 1960). Feeding sites are marked by large accumulations of sticky, wet fecal material. Despite their voracious appetite, larvae are not always as destructive as presumed. In California studies, feeding on celery during the first one-half of the growing season did not constitute loss because these petioles were routinely stripped from the plant at harvest (van Steenwyk and Toscano 1981). With cabbage, moderate defoliation prior to head formation is similarly irrelevant. In Texas, average population densities of 0.3 larvae per plant justify control (Kirby and Slosser 1984).

Hi Adam
A fine, detailed macro of this caterpillar. Good DOF to keep all of the subject sharp but to leave a nicely blurred background.
Kind Regards
Vinny

Hi Adam,
a fab macro of this bright green caterpillar.
Very sharp with great detail.
Excellent composition (though maybe it's been cropped a bit too tight on the left and bottom).
Great blurry BG.
Spot-on DOF.

Very well done!

Cheers,
Joe
