The Meadow Argus (Junonia villida) is a butterfly found in the Kingdom of Tonga in the South Pacific. I reared this one from the caterpillar stage. The butterfly is resting on my arm after being released. A few moments later, it flew up and away.
If it looks familiar to residents of North America, there’s good reason. It’s related to the Buckeye (Junonia coenia). One of the host plants for Meadow Argus is Porterweed (Stachytarpheta jamaicensis), a wonderful nectar plant that grows along roadsides and in empty fields on the island of Tongatapu, the main island of Tonga.
