Invertebrate - Diardi Heavy Jumping Spider - Hyllus diardi

Hyllus diardi, commonly known as the Heavy Jumping Spider, is a robust and captivating arachnid native to Southeast Asia. These spiders are prized by enthusiasts for their impressive size, striking appearance, and engaging hunting behavior. Heavy Jumping Spiders thrive in warm, humid environments with temperatures between 72–78°F and moderate humidity levels. Provide a terrestrial or semi-arboreal enclosure with adequate vertical space, cork bark, and live plants for climbing and web anchoring. Substrate should retain moisture without becoming waterlogged. Feed juveniles small insects like fruit flies and pinhead crickets; adults readily consume appropriately-sized crickets, roaches, and other arthropods. Offer food 2–3 times weekly and remove uneaten prey to prevent stress. Fresh water via misting or a shallow dish is essential. These spiders are generally docile and can be handled with care, though they may bite if threatened. Their excellent vision and curious nature make them rewarding to observe. With proper care, Hyllus diardi can live 1–2 years in captivity. Ideal for intermediate keepers seeking an active, visually striking invertebrate with straightforward husbandry requirements.
