It’s a strange irony that on 6^th April this field day was cancelled because of snow and was rescheduled only five weeks later weeks to fall on what will probably be one of the hottest days of the year, certainly the hottest so far.  An enthusiastic group of eight set off to Wrotham Water (National Trust reserve) and scaled the downs, counting plenty of slow worms as they went.There was also an excellent showing of butterflies and orchids.A couple of weeks earlier adders had been much in evidence but in the heat of mid-day they seem to have been keeping well back. On arrival at the lower reaches of the site, a moister and more shaded spot, we did at least find a very lethargic grass snake which offered a good photo opportunity for Fred.
