I’ve experimented with various ways of finding moths without light so here are some ideas
street lamp method
sometimes I can chance upon moths resting near street lamps (particularly geometrids and a lot of the micro moths). Plume moths are another one that’s usually easy to find resting on fences (or by flying into your home)
home invaders
I’ve had decent luck with just leaving windows open in spring and summer and having various noctuids, swifts, micros, geometrids, erebids etc fly in (but there’s the con of having to catch them out later).
sugaring
leaving a sweet and sugary mix on fenceposts, trees etc that can do good attracting a lot of catocala type moths, lots of noctuids and some micros (best to check around sunset and after) https://butterfly-conservation.org/news-and-blog/a-recipe-for-moths-sugaring-wine-roping
checking walls, trees and other surfaces
quite arduous and a hit or miss but it can work well (particularly in woodlands and with females of wingless spring species)
netting
just grabbing a net with small holes and running around like a madman at night with a torch to intercept any night flying moths, works surprisingly well but a bit awkward
checking flowers
works well both in the day and at night and I’ve spotted some lifer moths like that before
pheromone lures
can be a bit pricey but especially good if you’re looking for specific species like clearwings and emperor moths (in the same way you can raise certain native species and put virgin females in a net cage and wait for males to arrive)
beating around the bush (literally)
just smack around shrubs and bushes to disturb geometrids, micros and other more dainty moths, they usually settle nearby (similarly you can use a sheet for this)
caterpillar hunting
takes more time but you can grow caterpillars you find into moths (I’m doing this with some scarlet tiger moths right now with decent luck) but it can be a shame if they’re already infected with parasitoids.
I’ll add any more to the list if I can think of them but these are usually the best methods.
