Just a very small beetle, about 1/4 inch, but has great coloring. You can see where it got the name from. Sheild bug ( photo / image / picture from Kildale's Garden )
There are a great variety of these colourful beetles around. I'd rather have some of them than the Red Lily Beetles I've been getting for the last few years.
I know what you mean, although some of them are just the juveniles. ( photo / image / picture from Kildale's Garden ) ( photo / image / picture from Kildale's Garden ) ( photo / image / picture from Kildale's Garden ) ( photo / image / picture from Kildale's Garden )
