"Doodlebug, doodlebug, your house is on fire! Come out! Come out! Wherever you are!" As a child, this rhyme was my introduction to entomology, the study of insects. My mother, a south Mississippi country girl who migrated to Louisiana, instructed me to recite the passage while poking a straw into a doodlebug hole. Of course, to enhance the chances of catching this animal, you should always spit on the end of the straw first. For a five-year-old, the educational and entertainment value of this exercise is unsurpassed.
