The spring weather has been amazingly warm recently. As a result, within just a week nature has gotten its green dress back. Also the first leafs of Salix caprea have grown, making it finally easier to track back caterpillars. With the first leafs also the first feeding traces could be found.
Just a random check on a couple bushes and I found it: my second caterpillar of the Purple Emperor (Apatura iris). It felt great seeing the caterpillar happily feeding on it’s first feast after the long winter. Here’s a couple photos of the great day.
