Hyperodes maculicollis

Turf Symptoms

• Damage is usually limited to closely cut annual bluegrass.
• Brown patches of turf that do not respond to irrigation.
• Damage may be confused with Dollar spot disease.
• Adults can leave notches on leaf blades.
• Most damage occurs in May and June when first generation of ABW is present.
• Damage from larvae occurs on crowns (stems) and roots.
• Presence of brown excrement (frass) that looks similar to sawdust.
