A Japanese fan club for wasps has, according to Reuters, begun adding digger wasps to rice crackers, saying the result adds a waspish scent to the traditional fare.

The jibachi senbei, or digger wasp rice crackers, are made in Omachi town 200 km (120 miles) northwest of Tokyo and have five or six black digger wasps each, clearly visible to the naked eye.

A bag of 20 crackers costs 370 yen (1.60 pounds), but output may be limited as the wasps are caught in the wild for optimum flavour.
