October is the month when nights start cooling and many moths have taken their form for over-wintering. This can be as an egg, larva, pupa and some even hibernate in the winter as an adult. Numbers are much lower now but some moths may still be seen.
This is quite a large moth with wingspan 19 – 23 mm; it flies later in the year than other Thorns and is unlike any other moth flying this late in the year – from id September to December. Its habitat is broadleaved woodland including oak, hawthorn and birch so found in woods, parks and gardens. It spent last winter as an egg.
Another lovely moth to see this October as we have had mild southerly winds is the Silver Y – you can see how it gets its name from the picture! It also has a metallic sheen. Wingspan 13 – 21 mm, the larva eats many low growing plants including bedstraws, clover and nettle and it tends to breed in unshaded situations.
The third moth for this month is the Red-Green Carpet. This flies from September to November, wingspan 14 – 17 mm. It comes to ivy flowers and sallow catkins. Another moth whose larvae feeds on broadleaved trees mainly oak but also likes moorland regions. The females spend the winter as an adult.
