Die Zikade singt auf einem Baum an der Wetzelsdorfer Straße in Graz. Ich hörte sie auch an den drei folgenden Tagen an der gleichen Stelle, jeweils am späteren Nachmittag bei über 30 °C. Gesehen habe ich sie nicht.

🇨🇿 Věděl jsem, že se s touto kapradinou v údolí Kamenice setkám a rostla opravdu na mnoha místech ale tohle místo, pod zříceninou hradu Návarov, mi zcela vyrazilo dech. Desítky mohutných rostlin.
🇬🇧 I had known I'd find this fern in the Kamenice river valley and it indeed grew in many many places but this one, under the Navarov castle ruin, took my breath away. Dozens of large plants.
