Increased retreat construction
Reduced activity
Spending extended periods inside hammocks
Never disturb a spider during a molt.
Proper humidity is especially important during this stage.
Handling
Hyllus diardi is often considered one of the more handle-tolerant larger jumping spider species.
If handling is desired:

Move slowly
Avoid sudden motions
Support the spider carefully
Their larger size often makes them easier to interact with than smaller species.
Breeding
Captive breeding of Hyllus diardi is becoming increasingly popular but remains more challenging than breeding many Phidippus species.
Successful breeding requires:
Mature healthy adults
Proper environmental conditions
Careful introductions
Close observation
Because of their slower development and larger size, breeding projects require patience and planning.
