The Lady Bird Johnson Wildflower Center Fauna Project |
Seven participants enjoyed a cool, partly sunny morning during this survey. Some caterpillars have no prolegs (fleshy appendages that function as extra legs) in the middle of their body; they move by "looping" and are called loopers or inchworms. While all caterpillars in the family Geometridae do this, so do some in the family Noctuidae. The difference is in the number of prolegs at the rear end: geometrids (true inchworms) have only two pairs while noctuids have three or more (see images below).
