28-Spotted Ladybeetle and Other Leaf Eating Beetle Control
© Frances Michaels
This pest confuses gardeners because it looks like a ladybeetle syn. ladybird, one of the 'good bugs' but it
is definitely a pest. What gives it away is the skeletonised leaf where the pest has been feeding. If you are
still not sure than count the spots. The Common Spotted Ladybird, a 'good bug' only has 18 spots.
The eggs of the 28-Spotted Ladybeetle are laid under the leaves in a cluster the size of a 5 cent piece. The
larvae hatch out in about a week and look like little greenish-yellow hedgehogs and can seriously damage a
range of crops including cucurbits, beans, potatoes and tomatoes.
Most beetles are useful 'good bugs' but a few are leaf or flower eating. The pest group include Pumpkin
beetle, Red-shouldered leaf beetle (Monolepta australis
), Jewel beetle, Flea beetle, Figleaf beetle
and Orchid beetle.
