- •
We test the importance of dual UV peaks in Cosmophasis umbratica jumping spiders.
- •
Males have dual peaks in the UVB (280–315 nm) and UVA (315–400 nm) range.
- •
Both UV signals are used during female mate choice and male–male interactions.
- •
UVA signals, but not UVB signals, are used in sex recognition.
- •
UVA removal led to distinct changes in behaviour during interactions.
