Giant Jumping Spider

Hyllus diardi

About

The largest jumping spider commonly kept — a heavy-bodied Southeast Asian salticid with a big, photogenic face. Not a starter jumper: it wants it warmer (76-84°F, often a thermostat-controlled heat mat on the back panel) and more humid (70-80%) than a Phidippus, in a tall, well-ventilated enclosure with cork and plants. Lightly mist every day or two for even humidity and drinking droplets. Fast and bold but harmless, with mild venom. Best after you've kept a Phidippus first.
