Fire Chaser Beetles

It seems that God has created creatures to fill every possible need that can occur in nature. One of the most interesting of these is a beetle that is actually attracted to fires. According to the American Museum of Natural History, the beetle is of the genus Melanophila. People who live in areas where wildfires are frequent refer to them as “fire chaser beetles.”

When a fire occurs, the beetles sense its presence and fly toward it. They will lay their eggs in forest material that is still smoldering, or in material that has been recently burned. The biological explanation is that their eggs are safer from predators than they would be in an area that has not been burned, but how would they know that.

If you think about it, this beetle is a significant factor in the recovery of a burned area. One problem after wildfires is that much of the food for birds and mammals has been destroyed. The whole ecosystem has to be reset, and the eggs and baby beetles of Melanophila are at the bottom of the food chain. The fire chaser beetles’ ability to locate the fires involves an infrared detection system. Instead of flying away from the fire, as you would expect, they fly toward it.

How such a system could develop by natural selection is an interesting question. It seems that fire chaser beetles are part of God’s design to assist the recovery of burned-over areas.
