Norfolk Hawkers and much more at Filby......
A very pleasant and warm day at Filby (22nd) found the vegetation alongside the paths alive with Damselflies. Six species of damselfly (with estimated totals) were seen: 10 Red-eyed, 10 Common Blue, 100 Blue-tailed, 100 Variable, 20 Large Red but only 3 Azure.
However, the damselflies in and around the path-side vegetation ran the gauntlet of the many Tetragnatha aka stretch spiders (T. extensa/T. montana) lying in wait for a meal to arrive.
Of the larger Odonata, Four-spotted Chasers were the most numerous with 10 (estimated) seen, along with 5 Hairy Dragonflies and 4 teneral Norfolk Hawkers were the first of the year.
Butterflies included the first Speckled Wood (4) and Commas (3) of the year and a female Orange-tip, Red Admiral, Large White, Green-veined White and 3 Holly Blue were also present.
Several Alderflies were seen and Tachina fera, Wasp Beetle and Nomada flava were the first of the year, whilst a queen Hornet, which landed in the understory of the vegetation, made a fine photographic subject.
Hoverflies included Helophilus pendulus, Cheiosia variailis and the very orange-looking Parhelophilus frutetorum/versicolor and an Alder Sawfly Eriocampa ovata was also of note.
Whilst the main focus was on ‘Life in the Undergrowth’, Garden Warblers continued to sing in the wood and Great Crested Grebes and Common Terns were at Ormesby Little Broad.
