Which family is characterized by front legs broad and modified for digging with large claws, as seen in Mole Crickets?

• A. Gryllotalpidae (Mole Crickets)
• B. Gryllidae (Crickets)
• C. Phasmatodea (Walkingsticks)
• D. Notonectidae (Backswimmers)

Answer: (A)

The key idea is that digging through soil is made possible by specialized forelegs that are broad and shovel-like, a fossorial adaptation. In mole crickets, the front legs are widened and flattened into powerful spades with large claws on the inner edge, built to scoop, pry, and push soil as they burrow underground. This distinctive modification directly supports their subterranean lifestyle and explains why this family is the best fit for the description. The other groups don’t share this same digging-oriented foreleg anatomy. Crickets in general have legs suited for jumping and walking, not digging; walkingsticks are elongated and camouflaged for staying still in vegetation; backswimmers are aquatic and use their hind legs for swimming. The characteristic digging-ready front legs point to the mole crickets’ family.
