Ladybug vs Asian Beetle Checker

Spot patterns, M-marks, and behavior to tell ladybugs from Asian lady beetles.

Educational tool only — not medical, pest-control, or safety advice. When unsure, observe from a distance and photograph rather than handle.

Ladybug (lady beetle)

Often more consistent spot patterns and a glossily rounded shell. Many native species stay outdoors on plants hunting aphids.

  • Spot count often fairly consistent for the species
  • Pronotum usually without a bold black M/W mark
  • Less likely to swarm indoors in autumn

Asian lady beetle

Highly variable orange-to-red beetles that often show a white pronotum with a black M or W. Can gather on sunny walls in fall.

  • White pronotum with black M or W mark is a strong clue
  • Spot count and size vary widely
  • Often clusters on buildings in cooler weather
1. Look at the area behind the head (pronotum). What do you see?
2. Where did you find it?
3. How do the wing-cover spots look?

Educational comparison only. Color and spots vary within both groups — photograph with BugScout for a fuller estimate.
