Mark Barber wrote 'It's been a month since the first male adders were spotted at Oxwich and on cue the females have started emerging. The males tend to come out a month before the females to get ready for mating, soon the adders will shed their skins, disperse and breed. Females tend to be bigger than males. Females have a brown zig-zag and males have a black zig-zag. Whether it's frog spawn in your garden or a common lizard on your local heath, any amphibian or reptile sightings gratefully received at firstname.lastname@example.org Cheers, Mark'
