A doodlebug is a colloquial term that can refer to two different things: a type of insect or a device used for locating underground utility lines.
In the context of insects, a doodlebug is a crawler or an immature form of an insect, primarily used to describe the larva of the antlion, a winged insect of the family Myrmeleontidae. Antlions belong to the order of insects called Neuroptera. The doodlebug larva has a unique appearance, with a plump, segmented body covered in hairy bristles. Within its habitat, usually sandy or loose soil, the doodlebug constructs cone-shaped burrows and lies in wait at the bottom. It uses its large, sickle-shaped mandibles to snatch and devour unsuspecting prey that stumble into its trap. This intuitive method of hunting has given rise to its whimsical nickname, as observers sometimes witness this creature form countless intricate patterns or "doodles" with rapid, circular movements.
Outside the realm of insects, the term doodlebug can also refer to a device used for locating underground utility lines. Typically, it consists of a small rod or wand that emits a magnetic signal. This device is utilized by professional contractors or utility workers to detect the presence and path of buried utility lines before conducting any excavation work. By waving the doodlebug wand over the ground's surface, it emits an audible signal or vibration when it detects the magnetic field generated by metallic utility lines such as electrical cables, water pipes, or gas lines. This process helps prevent potential accidents or damages to existing infrastructure and ensures the safety of workers.
The word "doodlebug" has two main meanings with different etymologies.
1. In American English, "doodlebug" is a colloquial term for an insect, more specifically the larvae of an antlion. The term originated in the United States in the early 19th century. Its etymology comes from the fusion of two words:
- "Doodle" is derived from the dialect word "dudle" or "dudlet", meaning a small or feeble creature.
- "Bug" originates from Middle English "bugge", meaning a ghost or specter. Over time, it came to refer to various types of insects.
The combination of these two words resulted in "doodlebug" being an informal name for the antlion larvae due to their small size and creepy appearance.
2. In British English, "doodlebug" has a different meaning.
