2022-06-25 Holtug Kridtbrud (Stevns), Denmark Imago Different animals. Small size and on host plant Rundbælg (Anthyllis vulneraria) [Common Kidneyvetch ~ Vulneraria ~ Getväppling]. I'm not sure about sexes, but the last two photos are of the same animal, and the body looks fat indicating a female. Difficult to photograph this batch was. |

2023-06-12 Kalvebod Fælled, Denmark Imago Svenskeholmvej - pinseskoven. My first on Amager. Like it because I went out to look for it especially; although at another spot at first. Might be more in suited habitat, and even more so this year with the dry conditions everywhere. |
