Potter Wasp Is Building A Nest | Insects' Life.

A potter wasp (Delta conoideum) makes its nest by stacking mud in a specific manner and shaping it to give a pot like form. It collects mud and form a ball of mud with the aid of its long mandibles and fore legs. Holding the mud ball in between its mandibles and fore legs it flies to its nesting site and start stacking mud on the substrate by a beautiful simultaneous action of fore legs and mandibles. A number of times it goes and collects mud balls to make its nest step by step. After completion of nest making it sits on the nest/pot and inserts its abdomen into the nest and lays 1-2 eggs. Eggs generally hang from upper wall inside the nest. Then it starts collecting lepidopteran larvae (generally 5-6). It paralyzes larvae by stinging and brings them to the nest and inserts these larvae into the nest. This process occurs- one larva at a time. After storing the larvae it seals the nest opening by mud in similar way as it does in case of nest making. Like this way it builds other 5-6 nests adjacent to the first nest/pot. All nests are attached with the adjacent one, no spaces are there in between two nests.
