Just hear me out for a minute. After a few days, it came to me that cockroaches seem to be the most common yet viable bug throughout the seasons/year compared to other bugs. Let me list out a few benefits:

-Not as competitive in catching compared to other bugs (e.g butterflies, ladybugs) since cockroaches aren't spawned in public areas

-Easily found in the Railroad Cave (sometimes in bathrooms such as those in the Railroad Station), sometimes in groups

Catching a cockroach may take a few seconds to ~1 minute. Waiting until it hits a wall may help to stop its unique/complex movement for a few seconds. From those few days, I've caught >300 cockroaches that were sold for 9g each when in demand. This accumulated to >2,700g. Any thoughts?

Considering the 5->6g price of them supposedly added recently, I hope not  

Last year I was catching ~100 cockroaches in half an hour due to techniques and specific focus on highly populated areas. They are possible to 'farm,' but what I found is that the witch very seldom wants them. Also, if you have a trusted companion, try farming them with a partner - if you stand on a cockroach, it stops moving until you walk away, allowing your friend to catch it.
