Animals in Connecticut

Connecticut, the third-smallest state in the US, has not let its size come in the way of its wildlife population. Over 50% of the state is covered by forest, so naturally, it boasts a diverse flora and fauna. Most of the animals living here are native to the state, with some invasive species, like emerald ash borer, Asian longhorned beetle, and spotted lanternfly, also calling it home.
