Cycads
are some of the oldest plants on earth, and some, such as the sago
palm (Cycas revoluta) remain popular houseplants. These are tough,
rugged plants that can live for hundreds of years. However, a cycad threat has
emerged in the form of blue cycad butterflies (Theclinesthes onycha).
While these butterflies have been around a long time, only recently has cycad blue butterfly damage become a problem for gardeners.
Read on for more information about butterflies that damage cycad plants and tips on how to prevent this from happening.
About Blue Cycad Butterflies
Sago palms are usually the toughest of plants, but in recent
years gardeners have seen their cycads
looking sick. According to experts, the most likely cause is the presence
of butterflies on the plants. More specifically, blue cycad butterflies.
When you see butterflies on cycad, look at them carefully.
Recognize these butterflies by the bluish metallic sheen of their pale brown
wings. The back section of the wings has orange eye patterns. These are
responsible for the butterfly invasion on cycads.
Cycad Blue Butterfly Damage
It is not actually the butterflies that eat cycads though.
Instead, they will lay pale disk-shaped eggs on young, tender leaves. The eggs
hatch into green caterpillars
that grow darker as they mature and end up a brown-maroon color.
The caterpillars of this butterfly species hide during the
day under the leaves of the sago palm and in its crown. They come out at night
to eat the new flush of leaves. The attacked foliage turns yellow and the edges
turn pale and dry like straw.
Butterfly Invasion on Cycads
These butterflies have been around for years without causing
many problems, but suddenly people are reporting a butterfly invasion on their
plants. Fortunately, there are safe and easy solutions to protecting your sago
palm from caterpillars.
First, hose down your cycad’s crown regularly in the days
before a new flush of leaves emerge. This may wash off the eggs and prevent the
problem. Then, make up an insecticide using Dipel (or another insecticide based
on natural products derived from diseases of caterpillars) and a few drops of
dishwashing soap. Spray the new leaves as they unfold. Repeat the spray after
the rains until the new leaves harden off.
