Reservations please: insect hotels for overwintering friends

The temperature is dropping steadily each day and we are fast approaching hibernation time for several garden visitors who have, for the past number of months, called our garden their food bank, if not their home.
Some take their chances deep in the hedge or nestled under the ivy, but many will remain snug in a hideaway crack in an old wall, burrowed into the ground or snuck into a corner of the shed.
