Those lush little wads of greenery in your yard have it hard. To reproduce, male mosses must release their sperm into the dew and wait for them to trickle into a female moss, which is a separate plant altogether. Perhaps, if they’re lucky, the sperm might be given a lift by tiny arthropods called springtails, making their way through the moss patch.
Why the springtails get involved in this slow-motion seduction hasn’t been clear. But now researchers have found that just as flowers release scents that attract bees, butterflies, and other pollinators, so too does the humble moss lure in the springtail with its own special secretions.
