Twenty-spotted Lady Beetle (Psyllobora vigintimaculata)


Twenty-spotted Lady Beetle (Psyllobora vigintimaculata) on daisy. This tiny ladybug almost went unnoticed when I was watering flowers the other day. It wasn’t easy to get a photo and she crawled down headfirst into the flower bud. I suppose she was feeling shy!

After reading a bit more about these, I discovered the best place to look for them is at the base of skunk cabbage in early spring. AND, this is the best part. Later in the season, these little beetles switch to plants that have powdery mildew. They eat it. Definitely a garden friend!
