That little speck of debris you see is the home of a skilled architect from the inscet world: the bagworm. The bagworm is not really a worm, but the caterpillar of a moth. The caterpillar builds its home by spinning a cocoon of silk around itself, and dressing it up with sand, leaves, picecs of twig or lichen. There are nearly 40 species of bagworms in India, and each species has its own style of architecture.
The caterpillar can crawl around with its house. They build small protective cases in which they can hide. Also called case moths. Captured from my home garden which is a home of many species.
