|August Thorn and Purple Thorn|
When opening the trap first thing in the morning, the spotted flycatchers sit in the lilac or the plum tree and wait to twirl after any moth that is disturbed when lifting the sheet or moving an egg carton. If the flycatchers happen to be elsewhere, the swallows will swoop on any flapping insect, even if it just to catch and drop it after a few airborne yards. Care has to be taken while the whole moth-trap paraphernalia is carefully examined and moved from the lawn into cool shade otherwise that morning's rarity turns into an early bird's breakfast.
Dave Chesmore has identified this one as an August Thorn (Ennomos quercinaria) and a male as it is orange in colour. Ennomos is the Greek for ‘legal’ and quercinaria refers to the oak, the larval foodplant. The reason for naming it Ennomos would require a footnote containing a short lesson in taxonomy – all interesting but this is not the right place. It has two resting positions both shown in the photographs.
