The moth clock..

Those of us who put lights out in the evening to attract and monitor moth populations measure our year with the arrival and departure of new moth sp. 

They are always seasonal and sometimes their names give this away - July highflier or December moth are examples.

We move around the year following a clock of moths.

Last night, the first of the deliciously-named setaceous Hebrew characters of the year.

Last night 91 macro moths of 30 species.

New for the garden were lychnis and tawny-barred angle.

The ruby tiger (pictured here with dark arches and dun bar above) appears twice in the mothing clock - where there

are two generations, its flight season is May to July and August to April.

The beautiful canary-shouldered thorn (below) appears in one generation between July and October.
