This is just spectacularly bizarre. I’m not sure which is stranger, the results, or that the study was done in the first place. I’m very curious about an evolutionary explanation of how this came about (how did UVB transmission evolve?)
Spiders “talk” to potential mates using a type of light not visible to the human eye, scientists report.
A team found that male jumping spiders (Phintella vittata) are using ultraviolet B (UVB) rays to communicate with females.
While UVA rays are often used in animal communication, this is the first evidence that UVB light is also being used, the researchers said.
The study is published in the journal Current Biology.
