Reddit reviews Moths of Western North America

Bioquip.com sells good collecting lights.

I use (the DC version that I have cut the end off and replaced with alligator clips and run it off a boat/car battery (I forget which but they have a handle attached for transport and use a trickle charger to recharge when not in use. If I'm using a generator In use the ac version)

If I'm using a generator this is my preferred light

For a sheet setup cheap $2.00 white bed sheets from Walmart work just fine. My quick go anywhere setup is two shepherd hooks (get ones that thick solid prongs with good welds or they will bent when going into hard ground)

Attach the sheet at all four corners so it won't flap in the wind. Then one laying on the ground in front of the upright sheet as many land on the ground and crawl up

To hold the light I use this tripod (or you can use another shepherd hook)

You will also want a mallet to help get the shepherd hooks in the ground and headlamps to see what has landed on the sheet.

If in North America this is the best Moth book (hands down/no question) and could make another awesome alternative present
