Feature Creature: Diving Bell Spider
The Argyroneta aquatica lives among plants as it needs a place for its web, and feeds on crustaceans and aquatic insects. These aquatic arachnids are native to northern and central Europe through Siberia and Asia, and never attack humans unless provoked. Their painful bites can cause inflammation and sometimes fever. Mating season occurs during mid to late spring and in order to reproduce, a female Diving Bell Spider must create a suitable nest for her egg sack after she has mated. Which means she will have to take multiple trips to the water’s surface to make an air pocket big enough for her sack. The mother then guards the egg sack until her babies break their way out of the sack, which is about three to four weeks, much like spiders on land. Diving Bell spiderlings stay with their mother for a few molts until they have reached their peak of maturity and development. This is when they disperse, and start leading their own new lives by themselves.
