Wide-jawed Viciria caring her eggs

Scientifically named Viciria praemandibularis (Salticidae), this jumping spider is, by obvious reasons, commonly known as Wide-Jawed Viciria, and can be found in Singapore and Sulawesi.

As you can see in the pictures, this female Wide-jawed viciria is caring her eggs. In the Salticidae spiders maternal care of eggs and recently hatched juveniles appears to be widespread. Salticids spin silken eggsacs and stay with these, presumably guarding them. Exactly what salticid females guard against and how they guard the eggs is unclear, but the maternal female could probably deter many egg predators and parasitoids.
