I found Coleophora calycotomella (2 colonies) new to Britain in 2004, the first was just metres away from a colony of the critically endangered Coleophora wockeella, the second destroyed by housing. In Britain it is still only known from the original site. Death's Head Hawk and Crimson Speckled (both self-found by day) probably my most gripping macroleps. Shown the hothouse woodlouse Anchiphiloscia pilosa known from just one indoor site and the pill mill Adenomeris gibbosa. The tachinid Dexia vacua, so rare it was considered extinct in western Europe. Land Caddis (larva) self-found in Worcs. Birdwise, I've twitched several species that have only turned up once or twice in Britain, faves being Yellow-throated Vireo, Long-billed Murrelet, Naumann's and Red-throated Thrushes. Self-found Scops Owl (1am at Porthgwarra) and Black-browed Albatross (sat on the sea off Orkney) also rather pleasing. In 2016 I was boat crew on Scillies, resulting in 30+ Wilson's Petrels across numerous pelagics. Alpine Rock-cress, Iceland-purslane, Least Adder's Tongue, New Forest Bladderwort, Spiked Rampion, Scilly Pigmyweed, Marshall's Eyebright and Dwarf Pansy all très cool plants. Stinking Goosefoot truly does. I self-found Mitella ovalis growing wild on Skye, it was subsequently added to the British list (2017). I then found the fungus Phyllosticta crinodendrin, also new to Britain (2018), on Skye and added Marionfyfea adventor to the Scottish list. Self-found many Hyperia galba inside Comb Jellies, plus Pennella filosa (an ectoparasite of Ocean Sunfish), two 80lb Porbeagles (tagged) and many Portuguese Men o' War, all in Scillonian waters. Many Scilly Shrews, 3 Scottish Wildcats, a Beluga, a Northern Bottlenose Whale, an adult male Walrus and a Bearded Seal are mammal highlights (last four were twitched). Dicranopalpus ramosus, caudatus and larvatus in the space of 5 days a new personal best! Yellow-tailed Scorpions were very pleasing to see and handle. Plus a Black Panther in Cornwall, seen but not on my list.
