In Animal Crossing: New Horizons, Blathers isn't with you from the start, and when he does arrive, he won't have a museum to begin with! Here's how you assist Blathers to get the museum started.
How can you get Blathers to come to your island?
One of the first things you do is add Blathers to your island. Simply complete the missions given to you by Tom Nook in the game's prologue to position your tent, assist your new neighbors, and prepare for the party by collecting sticks and fruits. You can now talk to Tom Nook about using his crafting table after you've slept and gotten through your first full day. He will give you the ACNH DIY recipe for a variety of items in Animal Crossing, including a flimsy net and a flimsy fishing rod, and will ask you to bring him something you catch. If you bring him a new creature, he'll ask if he can give it to a "mate" of his, and if you agree, he'll reward you with new Animal Crossing items and DIY recipes. When you bring him five animals, he'll get a phone call, it's Blathers!

During the day, butterflies will flutter about gently. Snag them in your net!
A moth can almost always be detected by the light outside the Resident Services tent at night.
Snails can be found camped out on rocks, particularly when it rains.
Conch-like shells on the beach can turn out to be hermit crabs at night. Capture them in your net.
When you smack a rock with a shovel, pillbugs or centipedes can appear.
Shake the trees and bagworms and spiders can fall out, allowing you to quickly snag them in your net.
When shaking leaves, take care not to knock a wasps n
