Jumping spider (Trite parvula) House hopper
Synonym: Euophrys parvula
Binomial name: Trite parvula
Common name: House hopper
Trite parvula (Euophrys parvula) was is a small, relatively common NZ jumping spider found in the North Island and as fr south as Christchurch. Jumping spiders have the keenest eyesight of all spiders, with eyes that are capable of forming images. This excellent eyesight is important as jumping spiders actively hunt their prey during daylight. As their name suggests, jumping spiders are capable of leaping large distances when they pounce on their prey.
A Trite parvula can jump 5cm onto a fly. The photo below shows a spider with a house fly that it has jumped on and is injecting a paralising poison. Note the silk saftey line that is attached to its silk spinnerets.
