I caught a caterpillar eating my WP over Christmas. I identified it as that of an Angle Shades moth Phlogophora meticulosa, and suspect it came from a nearby fern, which I know was showing some caterpillar damage in the autumn (ferns are listed as food plants). Thankfully, it had only eaten half a leaflet, but looked pretty sick as a result (didn’t hide away during daylight as is usual). Has anyone else in Europe caught anything eating their WPs? Have they proved susceptible to any leaf eating inverts back in Oz?
