It was filled with old egg cartons and the cardboard cover from the huge mercury vapour bulb that sits shining on the trap top. This gives the moths something to rest on while in the trap. Perspex baffles prevent the moths escaping once they have been attracted to the bulb and fallen into the box.
A timer is set, 9pm on, 4.30am off. It is as easy as that!
In the morning it is a case of identification, listing and then photographing the most interesting individuals.
To do this properly you need to be in control of the situation and this was the perfect excuse to build a temporary studio!
In the picture is my dad with a Canon EOS 1D Mk 3 with a 180mm macro lens on the front.
It's on top of a Manfrotto tripod with a pan and tilt head. Connected to the camera is a 580 speedlight flashgun with a diffuser. A twig for the moths to perch on was held in a Wimberley Plamp to allow it to be moved around so the camera could remain in it's fixed position. A mirror was placed underneath the perch to reflect the flash.
Once this had been set up the moth was placed on the perch and the photography could start.
