Scarlet Tiger Moth

One large and beautiful moth seems to be bucking the trend for moth numbers this year. More...

So far, 2024 has been a very bad year for insects. There are many reasons for this, but the weather has been particularly hard on moths and butterflies with numbers way down on "normal" years. The Scarlet Tiger Moth, Callimorpha dominula, is a vividly-coloured day-flying species, with a single generation on the wing in May and June. Its larvae feed on a number of herbaceous plant species, but especially Comfrey. In contrast to other moths, the Scarlet Tiger seems to be having a better than average year, as can be seen from the Species data profile (bear in mind that the 2024 numbers are still incomplete):

Why is this? This species has been increasing in Leicestershire and Rutland over the past decade but quite how it has managed to do so well this year is unclear. More data will help to monitor trends in species data so please keep your eyes open for Scarlet Tigers.
