I am always amazed that people behave as if butterflies and moths do not exist. They do not see them. I put it down to dull self-concern in most cases, in the others, to a habit of mind in which any possible flutter or figment has been resolutely excluded. - Niall Duthie, Lobster Moth 1961 Light Emerald Campaea margaritata (Linnaeus, 1767) Wingspan 30-40 mm. An attractive pale-green species, which has a blood-red tip to the forewing, sometimes extending as a line along the outer edge of both fore and hindwings. It is quite commonly distributed throughout most of the British Isles, and flies from June to August.
