Small but terrible
What’s small, has shiny bright red wings, a black head and legs and is capable of destroying a lot of ornamental plants? It’s the red lily beetle and it’s the terror of many gardeners worldwide.
Also known as the lily leaf beetle, this small insect is notorious in areas where lilies are cultivated. First seen in Montreal, the red lily beetle has spread throughout Canada and in some parts of the United States.
“They are often confused with the cardinal beetles since they also have a black underside and wings that are spotless and red in color. However, lily leaf beetles have wings that are shinier with tiny dimples on them. They are more rounded in shape compared to the dull, narrow, flattened and elongated cardinal beetle,” according to the editors of Wikipedia.
“Another difference between the two is their food preference. Lily leaf beetles are herbivores and are usually found on lily plants eating their leaves whereas cardinal beetles are usually found on tree barks and flowers and feed on flying insects. Lastly, the cardinal beetle has comb-like antennae,” they added.
As its name implies, the red lily beetle has a voracious appetite for lilies. Females can lay up to 450 eggs each season or about 12 eggs on the backside of each lily leaf. In this way, the eggs are concealed from predators. For extra protection, they are also covered with a thick brown substance.
The eggs hatch in about six days. The larvae start to feed under the leaf for the next 24 days until they finish the rest of the plant.
“They then burrow themselves in the ground to pupate in a cocoon formed by saliva and small particles of soil. In about 20 days, they emerge as adults and continue to feed until winter. In some cases, they are able to go through this cycle more than once in a single year,” said Wikipedia.
The damage left by this small insect is by no means minor. It can leave lilies weakened and susceptible to diseases.
The Royal Horticultural Society of Britain has recently spotted this pest destroying large areas of ornamental gardens. Unfortunately, this insect is difficult to eradicate and gardeners are usually advised to avoid planting susceptible plants.
“Once a garden is infected, it is incredibly difficult to grow plants without using dangerous pesticides that risk affecting other insects and beetles,” said Oliver Gregory of the Telegraph.Co.UK.
So don’t be surprised if your florist runs out of lilies one of these days. It’s probably due to brisk sales or the onslaught of red lily beetles. To satisfy your need for flowers, take your pick from other beautiful blooms instead.
