It really depends on what kind of insect or arthropod you are interested in.

Are you into herbivore or carnivore?

For herbivore, you can try silkworm, and butterfly.

For carnivore,
I would recommend mantis. They are awesome looking, and they can be easily accepted by more people than if you have a tarantula.





For typical insects and arthropods, old newspaper or magazines will do just fine as substrate.
