Doodlebug is just another name for antlion. They live in the dusty dry places around our homes and trees. Several are visiting our classroom during our dinosaur theme.
We watched our antlions doodle around in a shallow bowl before adding them to their habitat. They set traps while the students watched.
The stick in the container is for an antlion to perch on should it change to the adult stage while in our classroom. The white cylinder is a film casing with a hole in the bottom so water can be added without making the sand on the surface wet.
Antlions can remain underground for one to two years. Once they go into the cocoon stage, they will emerge as adults in about 28 days.
