1. Who am I? Can you identify these Illinois critters? T. Trimpe 2008 http://sciencespot.net/

2. Only the males of my species “sing” or make a noise that attracts females. As an adult I usually don’t eat, but am a tasty treat for songbirds. I can remain in the ground as a nymph for as many as 17 years. People often mistakenly call me a locust. Do you know who I am? Cicada http://www.dnr.state.wi.us/org/caer/ce/eek/critter/index.htm

3. I am the world's-largest land-dwelling salamander. I live in prairie ponds, marshes, lakes, and woodland ponds. I am somewhat of a chameleon as my colors and patterns can change throughout my lifecycle. When I am young, I am definitely spotted, but my spots turn to bars (like a tiger) or irregular blotches. I am the Illinois state amphibian. Do you know who I am? http://www.dnr.state.wi.us/org/caer/ce/eek/critter/index.htm Tiger Salamander

4. I can live 20-30 years and grow to be the size of dinner plates. I don’t have external ears but use my shell (carapace) to conduct low-frequency vibrations to the middle ear. I can dive up to 2 meters and stay under as long as an hour. I may be “painted”, but I’m not artwork. I am the Illinois state reptile.
