Another low count of single digit numbers. I'll try and post a picture of the set up later for suggestions on what might be the issue (or maybe it is purely location driven) but a homemade Skinner trap with 2 x 30W bulbs, 10 cm clearance between bottom of box and bottom of gulley, eggboxes stacked only under the gulley sides. The only things I can think of to check with others are:
- I'm checking trap at circa 6:30am, would earlier make any difference (assume not as the moths should effectively be in the eggboxes anyway come daylight)
- There is no perspex cover sitting above the bulbs so the unit is open across the top, does that make a difference to catch (several units online don't have a cover so assume not)
Another modest catch for me this morning, 57 of 24 species with Small Phoenix and Cloaked Minor NFY the highlights.
Still hardly catching any yellow underwings of any variety.
Andy - I have never had Straw Underwing here but a friend caught one four miles away on Sunday night. The recent Atlas map suggests it should be commoner than that.
All this talk of the scarcity of Straw Underwing has got me worried - I’ve been getting a couple each night recently. This is one isn’t it? (please excuse poor photo) Its hindwings were pale yellow.
Not uncommon down here. That said a number of commoner moths can start to slip away without being noticed as a result of excessive chemical use, habitat loss, etc....
All the best
