The Heavy Jumping Spider is a large jumping spider widely distributed across Southeast Asia. Its brownish-gray body is scattered with metallic yellow hairs that shift in appearance with the light, giving it a striking look. Females carry a horn-like tuft of black hair beneath their posterior median eyes, making it easy to tell them apart from males. With its large eyes constantly surveying its surroundings and quick, precise jumps when hunting, it has real presence and personality among jumping spiders. It thrives in hot, humid conditions and needs more careful humidity management than other species in its genus, which is why it's considered suitable for intermediate keepers. This species rewards anyone willing to stay on top of humidity control.

7 things to know before welcoming a Heavy Jumping Spider
1High Humidity Is Essential
This species needs more humidity than other spiders in its genus. A cage that's allowed to dry out can cause it to lose condition, so set up a way to maintain humidity, such as regular misting, before bringing one home.
2Keeping It Warm
Since this species prefers warm, humid conditions, heating support is essential during cooler seasons. Plan a cage setup that lets you manage temperature and humidity together for peace of mind.
3A Striking Appearance
Its brownish-gray body is dotted with metallic yellow hairs that catch the light differently depending on the angle. Females also have a distinctive horn-like tuft of black hair below their posterior median eyes, rewarding close observation.
4Quick Movement and Sharp Eyesight
Like other jumping spiders, it has large eyes that let it carefully watch its surroundings, and it moves quickly using its strong jumping ability. It often reacts to its keeper's movements, making daily observation enjoyable.
5Keep Individually
Jumping spiders are generally territorial and solitary, so keeping multiple individuals in the same enclosure risks cannibalism. Provide one enclosure per spider.
6Feeding Frequency and Diet
Live prey such as crickets forms the core of its diet. Adjust prey size and feeding frequency to the individual's size and appetite, and remove any uneaten prey from the enclosure promptly.
7Prepare the Enclosure First
To avoid scrambling after bringing your spider home, prepare the enclosure in advance with good ventilation, humidity retention, climbing surfaces, and a hiding spot. Installing a thermometer and hygrometer also makes ongoing care easier.
