Red Underwing

It may not have the striking colouration of a hawkmoth but at 4cm long the red underwing (Catocala nupta) is one of our larger moths.  A night flier it was resting quietly, on a warm and sunny day, on the shaded side of a Newburn Riverside Country Park noticeboard.  They can be found feeding on flowers in the early evening but it was much too early in the day for this sort of activity! It has a red underwing (unsurprisingly) but this was certainly not on show as it tried to blend in to its background.

The red underwing is a common species in the south of the UK but in the north-east there are a just a scattering of records, more in recent years but perhaps this is more to do with recording than an actual increase in numbers?

    I wonder if they have become more noticeable due to some decrease in the trees against which their camouflage blends perfectly?

  2. Is it actually red under its wing?

      The lower wing is red on top but you can only just see a tiny part of the white and black margin at the middle bottom. Were it to have opened its wings a little the red would have been revealed.
