@YannC Yes! They always look like they are smiling 🖤 💛 🖤 I used to encounter them by chance. This year, I tried for the first time deliberately... and it&#39;s not that hard. You can check on iNaturalist where they are often observed: https://www.inaturalist.org/observations?subview=map&amp;taxon_id=27726 Best time to see them is at night after rain, when it&#39;s below 18 degrees.
