Cycad blue butterfl y

Now that cycads are increasingly

opular, more gardeners have

problem with the caterpillar of

he cycad blue butterfl y eating or

keletonising new shoots. When a

ycad gets only one fl ush of leaves

year, that’s a disaster. Watch

ut for the small blue butterfl ies

overing around the plants.

Consider spraying new growth

with an organic caterpillar control

very two weeks. Alternatively,

over the emerging fronds with

est-exclusion netting, ensuring

t stays clear of the growing

ronds. Once the new leaves

ave hardened off, they aren’t

sually attractive to the butterfl y

nd the netting can be removed.
