Wasp nest morphology
The nest is constructed onto something sturdy -a tree, a post, part of a building and it expands layer by layer as the female wasp collects mud or wood fibres in her mouth and regurgitates them. She constructs cells within the nest to house her larvae. During the winter most of the wasps die except the queen, who hibernates. In preparation she catches spiders to feed her larvae. She encases the live, paralysed prey in the cells with her larvae for them to feed on once they mature. The nest degrades during winter and must be rebuilt yearly.
