Salticidae - jumping spedersThis fossil amber displays a pair of Jumping Spiders some 5 mm and 3 mm in length. They are members of the Family Salticidae, a name derived from saltere (to jump). They sneak up on their prey, then pounce, earning them the name Jumping Spiders. They are accompanied by a tiny wasp and a dark-winged fungus gnat. Spiders are usually found where there are insects, such as here as inclusions in fossil amber.
