There are a lot of different Beetles (350.000 Arten in 179 Familien sind beschrieben)
All of them do breath oxygen via Trachea. Even all the Beetles that live under water need to breath oxygen. They have different technics to do that. E.g. taking small oxygen bubbles with them under water.
the biggest one is the Titanus giganteus (Riesenbockkäfer) that measures 170 mm.
some have wings, some don't.
Sensing
Some beetles have very beautiful colors. e.g. (Carabus problematicus)
All beetles do have feelers. With that they can sense contacts and some can also breath with it. The can't see very well. But especially night active beetles can also see at night, so that they can find female partners that for example can glow. Firefly - (Lampyris noctiluca)
All of the sensing organs are used to find partners or food.
There are some that can sense fire. Some can feel the change of temperature others can hear the noise of fire. The do that to find mates and place their larvaes into the burned wood. (special australian beetles)
-They communicate via pheromone and sound...
You fist have to decide what kind of beetle you want to work with because there are soo many different kinds!
