Butterfly bait traps versus zigzag walks: What is the better way to monitor common and threatened butterflies in non-tropical regions?

摘要: Trapping live butterflies using bait traps is a traditional monitoring method used in tropical regions. We compared the utility of with zigzag walks temperate Central Europe where butterfly have not been systematically tested yet. focused on communities steppes, forest steppes and open woodlands. carried out research seven localities during 2–4 consecutive days summer 2013. observed far fewer specimens (538) than (2115), but more species (34 vs. 23), genera (27 18), as well families (8 5). However, overall composition was influenced by only locality. For 8 37 detected diurnal were efficient walks. Most trapped individuals sampled from Nymphalidae attracted to both types various ratios.

Also, some common rare recorded eight Czech Red list threatened one priority European Union interest combining methods. are convinced that combination standard procedure would lead an improvement detectability provide accurate estimation actual abundance.
