Do you know Tennessee's official state symbols?

Clue (sport fish): This fish has been the Volunteer State's official game fish since 2005 when it replaced its larger-mouthed cousin, which is still the official fish for several other states. Tennessee is the only state to honor this fish as its own.

Clue (state commercial fish): This fish is the most highly populated throughout the United States, which makes sense when one learns it's the official state fish of not just Tennessee but Kansas, Missouri, Iowa, and Nebraska, as well. As eating opportunists, they can wreak havoc if they're introduced to non-native waterways. These fish stand out for having no scales and being monogamous for life. 

Answers: Smallmouth bass (sport fish), channel catfish (state commercial fish)

State insect #1: This species displays a variety of defense mechanisms against predators. These include producing a sticky substance to entangle predators in, and a foul odor to repel them. Additionally, males of this insect emit a targeted flash to locate females to mate with, pairing up with a partner once a female responds with a flash of her own.

State insect #2: This species is one of the biggest predators of aphids, and as such, has been used for pest-control against them, similarly to the convergent lady beetle. It completes overwintering in forest edges, among ground litter, and under rocks and tree bark.

State agricultural insect: This insect is an invasive species in many non-native areas it inhabits, often displacing native birds and insects. It is the third insect to have its genome mapped, following the fruit fly and mosquito.

State butterfly: This species hovers closely to pawpaw trees, which provide a crucial food source for adults and young. It can be recognized by the ‘swordlike’ tails that extend from its greenish-white wings.
