A trip following bats along the river Cam has become one of the hottest tickets in town – and raised money for their protection

It’s an impossibly idyllic early summer evening on the Backs of Cambridge. A blackbird flutes as a man pressure-washes a table outside a hotel. Mating flies drift on the breeze, alongside a whiff of marijuana. A student lies flat on the riverbank, feet in the water.

Punting on the river Cam has stopped for the night but one boat slips into the gathering dusk: the Bat Punt Safari.

A pond skater’s feet feel prey landing on the drumskin-tight surface of the water. Just how can this skater skate on thin “ice” while a fly the size of its eye falls through? Though the fly tries to drag its legs free, surface tension binds it to a sheet of elastic glue.

I lean forward and the skater darts away in a series of fitful starts. A water measurer beneath my gaze stays put at the pond’s edge. An aquatic stick insect, Hydrometra stagnorum could easily be mistaken for a strand of dark human hair. My eyes are just a handspan away, so I can observe the detail of alternating light and dark strips along its abdomen, which remind me of a ruler.
