A very good question, I would say 90% arrive at the sheet or just below it. I'm using a glide cam attachment on the camera which allows me a free hand and freedom to look down when i move and I take great care not to tread on things. Inevitably some do perish though. By far the most important thing to avoid carnage is to be up at around 4am before sunrise in order to switch off the bulb and allow everything to fly away again before birds wake up and have a free feast.
Incredible! It's like Indiana Jones and The Temple of Doom! Did it feel like you were stepping on fortune cookies at all? ;-) Also, that cicada at 9:23 sounded like a 90's printer. lol
Hallo Richard ! I like Your video very much. May I use just the sound from Your video for my exibition of the photos of night moths ? It will be in Prague, Czech republic next week. Marianna
