This impressive male Golden-ringed Dragonfly was hanging out in a bog near Loch Morar (which incidentally is the deepest freshwater body in the British Isles with a maximum depth of over 1,000ft). Females have a distinctive 'spiked' vulvar scale, diagnostic of the genus, which aids in the oviposition of eggs in streams and ditches. The larvae of this species live for 3-7 years before emerging as adult dragonflies. (c) Richard Brown
Keeled Skimmers were abundant in the same bog, with multiple females egg-laying in the shallow ditches. The smart males, such as this one, were duelling it out over the prime stretches. Keeled Skimmers are common in Southern Europe, but only locally common in Western Britain and Ireland. (c) Richard Brown.
Perhaps the most confiding of all the Dragonflies on the bog was this female Northern Emerald (thanks Andrew!). Although not very visible in this photograph, the two large yellow spots on the third abdominal segment and a broader waist readily separate it from the male of this species. In the UK it is confined to north-west Scotland. (C) Giselle Eagle
