A total of 326 species were recorded during the year, mostly from leafmines and light trapping undertaken on the Golf Course on 10 occasions. A remarkable 46 new species were added to the Warren list, including six ‘macro’ moths.
These included a number of presumably overlooked common species such as Mottled Grey Chloroclysta multistrigaria, Garden Rose Tortrix Acleris variegana and Sycamore Piercer Pammene aurita; as well as two introduced adventive species Cypress-tip Moth Argyresthia cupressella from North America and Ruddy Streak Tachystola acroxantha from Australia.
Other more local firsts included Centre-barred Sallow Atethmia centrago, Early Long-horn Adela cuprella, the first confirmed Dusky Thorn Ennomos fuscantaria, Little Slender Calybites phasianipennella, New Oak Slender Caloptilia robustella and Pale Eggar Trichiura crataegi.
Rarer discoveries included three Aethes deaurana, the 10-12th UK records, probably established on site feeding on Alexanders; and three nationally scarce species, Horse Chestnut Pachycnemia hippocastanaria, the first confirmed record for this heathland specialist, New Marsh Cosmet Cosmopterix scribaiella, new to Devon and Sorrel Midget Enteucha acetosae.
Other species recorded included local specialties such as Crescent Dart Agrotis trux, Shore Wainscot Mythimna litoralis, Dusky Aroga velocella and Beautiful Groundling Caryocolum marmoreum, Hoary Gymnancyla canella, Sandhill Anerastia lotella and Gorse Knot-horn Pempelia genistella and Sea-rush Case-bearer Coleophora maritimella.
More familiar species included Scarlet Callimorpha dominula and Jersey Tiger Euplagia quadripunctaria, Blood-vein Timandra comae, Rosy Footman Miltochrista miniata, Old Lady Mormo maura and Pale Calliteara pudibunda and Nut-tree Tussock Colocasia coryli.
The clear pick of the migrants was the first Clifden Nonpareil Catocala fraxini for the Recording Area in early September, but another first, Black-tipped Ermine Yponomeuta plumbella, was presumably also a migrant as the foodplant, Spindle, does not occur on site.
The first Diamondback Plutella xylostella was on 1 Apr, with the first Silver Y Autographa gamma in early June with records through to November with a peak in early September, a Dark Sword-grass Agrotis ipsilon was trapped in mid-August, single Gem Nycterosea obstipata and Scarce Bordered Straw Helicoverpa armigera were with the Clifden with several Vestal Rhodometra sacraria and a few Rush Veneer Nomophila noctuella. A Convolvulus Hawkmoth Agrius convolvuli was found in late September along with the first Rusty-dot Pearl Udea ferrugalis.
