Exotic scale on grey mangroves
Ceroplastes sinensis
-38.3748, 145.221
Field Notes
Description:
Scale insects on mangrove trees. At least two forms here? The small ones were about 1 to 2 mm - white when small and showing red within the protrusions when slightly larger. The ones attached to the stems (mostly but not exclusively) were much larger - perhaps 7mm diameter- they had indentations - one on top and six around the base.
Habitat:
On mangrove trees just above any possible high tide (20cm).
Notes:
These mangroves ('Grey mangrove' - Avicennia marina) are reputedly the southern-most mangroves in the world.
This waxy scale is introduced and was first seen in Sydney, Australia in 1966. A serious pest to citrus now it is infesting our mangroves !!!?
The small white ones are 2nd-instars and the 'red' bodied ones are 3rd-instars. The large waxy ones are adult females.
