Spider sex using ultraviolet B (UVB) rays

Professor Daiqin Li, from the National University of Singapore and his team have discovered that male jumping spiders (Phintella vittata) are using ultraviolet B (UVB) rays to communicate with females. The researchers found that females were more likely to mate with males that could "talk" to them with UVB compared with spiders sitting in chambers. The full details appear in Current science
