Alder Moth (Acronicta alni)

Filed under: Moths — Andrew Masterman @ 12:47 pm

The Alder Moth (Acronicta alni) is a medium sized greyish noctuid  with areas of darker markings which are diagnostic.

The Alder Moth is found in broadleaved woodland and scrub, often on poorly drained ground. The NBN Gateway shows its distribution to be confined to England & Wales where is is thinly distributed and local but Waring & Townsend does state that it is recorded from SW Scotland.

Recent records of Alder Moth in SW Scotland are:

  • 1 adult 17 May 2008 at Taynish NNR (Andrew Masterman)
  • 1 adult 28 June 2008 at RSPB Lochwinnoch (Paula Baker)
  • larval record 26 August 2007 at RSPB Lochwinnoch (Paula Baker)
  • 1 adult 3 June 2007 at Isle of Bute.

The Alder Moth doesn’t just feed on Alder but also on other broadleaved trees too including Downy birch, Goat Willow, Oaks & Elms.

Given its distribution being confined to a few sites in SW Scotland and the ubiquitousness of its foodplants, the Alder Moth is a species which is likely to have been expanding its range due to climate warming in recent decades so any new records elswhere in Scotland would be interesting. If you have any Scottish Alder moth records, please add them to this post in a comment below.

  1. I believe I may have found an Alder Moth caterpillar here in the Northwest. We had stopped to take a look at a fallen log/bridge over a swimming hole on the way to Buck lake (Mt.Hood) when I spotted it. It was fairly eye catching with a smooth black body, yellow stripes and fuzzy antler like antennae on both ends, with a few less pronged long hairs sticking out here and there. I’m used to seeing the very furry orange and black caterpillars so this one was interesting enough to photograph. I’m expecting my friend to send me the picture any day now, but would gladly send it your way for confirmation. I know this species could easily be confused with another, (can’t recall the name of the top of my head) but I feel quite certain it’s an Alder Moth.
