Day 4 of the 2025 #dragonfly #AdventCalendar. An immature Black-tailed Skimmer settling in to roost at the wonderful #Wiltshire #WildlifeTrust reserve at #LowerMoor Farm in early June. Males turn blue after a few days while females retain this black and yellow stripy pattern. #DragonflyAdventCalendar #invertebrates #ukwildlife #wildlife #insects #invertebrates #wildlifephotography #photography
