The Entomologist (1830), George Spratt.
The Entomologist is made from the objects of his own fascination.
Case Moth caterpillars, family Psychidae, use silk and plant materials to build a case around themselves, and extend their head and thorax to feed. There is a rear opening for excreta.
This individual, probably Clania lewinii has fixed its case to the branch with a loop of silk. When disturbed it retreated inside the case, and tightened the loop, drawing the case opening up under the twig. Neat.
textless: These tiny hoppers are among the last insects to disappear in the fall, and the first to come out in the spring.
The stick insect, Timema poppensis, moves into camouflage position on a redwood tree (Sequoia sempervirens) in the winning image in the 2013 BMC Ecology photography contest.
