Hello this is my bug guide, it may not be perfect but can still e a good source of information...
How to get the bug net:
In the south east corner of Mod Town, you will find A treehouse called Adam's treehouse, go inside and talk to adam, and he will give you the bug net.
How to sell bugs:
Go to Beryl's treehouse in swamptown, while inside equip the bug(s) you wish to sell, then tap the bug, she will ask you to sell... Also, if you talk to her, everyday, she ill have a different bug she needs, so Beryl will pay extra for it.
