Which pest is described as dull grey to black beetles with a long snout, with larvae that are legless and white having a yellow to brown head capsule?

• A. Bluegrass billbug
• B. Hairy chinch bug
• C. Ants
• D. Sod webworm

Answer: (A)

The combination of an adult with a dull grey to black body and a long snout, plus a larva that is legless and white with a yellow to brown head capsule, points to bluegrass billbug. This pairing is characteristic of billbugs (weevils): the long snout identifies them as a weevil, and their larvae are white, legless grubs with a distinct yellow-brown head capsule that feed on turfgrass roots and crowns.

Hairy chinch bugs are true bugs with different immature forms and feeding habits (not legless white larvae with a yellow head). Sod webworms are caterpillars (lepidopteran larvae) with legs and different coloration, and ants don’t match this description of larval form in turfgrass contexts.
