Convergent Lady Beetle

Hippodamia convergens

Also known as Convergent Ladybird, Convergent Ladybird Beetle

Convergent lady beetles are recognizable by the two white lines converging on their black pronotum and play a vital role as natural pest control across North America. Thousands of adults frequently gather in dramatic overwintering aggregations along cool mountain ridges, resting together under leaf litter and logs until spring warmth triggers dispersal. When threatened, these beetles release a foul-tasting yellow fluid from their leg joints to deter potential predators.

Responsible observation

Spring garden search: Look for adults and larvae on aphid-infested garden plants and agricultural crops during warm spring months.
Mountain winter aggregations: Avoid disturbing dense clusters aggregating along mountain ridges or beneath forest leaf litter during winter.
Gentle handling: Handle lightly without squeezing, as stressed beetles secrete a bitter yellow fluid from their leg joints.
