Females will add new cells one by one to the nest after each cell is provisioned. They provision these nests with spiders, such as crab spiders, orb-weaver spiders and jumping spiders in particular, as food for the developing larvae. Each mud cell contains one egg and is provided with several prey items. Females of some species lay a modest average of 15 eggs over their whole lifespan. Various parasites attack these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging. As is the case with many insect genera, there are man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
