Agrias butterfly

The agrias butterfly is a bug you catch flying near flowers. In the northern hemisphere look for it in Apr – Sep, from 8 AM – 5 PM. It hides when it rains. It can only appear after you have caught 20 bugs. Nook's Cranny pays 3,000 Bells, Flick pays 4,500 Bells.

Shows up around flowers in the daytime on dry days once you have logged 20 bug catches. Hold A to creep in slowly, let go to swing, and sell it to Flick for 4,500 Bells.
