Sphinx pinastri

They should be kept in a small plastic tub or petri dish. Do not add any leaves as this can kill the eggs. On hatching leave the larvae to eat the eggs shell if they want. You can also see the caterpillars developing in the clear egg shell.

Larval feed on scots pine, please make sure you can get hold of this, the bark is like a red colour.

Place kitchen roll on bottom of container, and stand the food up. This way the caterpillars are not sitting in their poo.
Clean the tub daily removing any old food plants and replacing with new. Any food with caterpillars on place back into tub, do not try to pick them of , as this can hurt their legs.

By the time they have moulted to l3 they can be placed into a mesh pop up and the plant food placed into a jam jar with water and stones make sure the water does not come above the stones.

Larval moult usually around 4 times to instar 5. They will be still for several days before walking out of their old skins.

Before beginning to make their cocoon, they will wander around and do a watery faecal movement.

You need to place a deep tub with mud in and leaf litter on top.
They will dig down into this and make their cocoons.

This needs to be stored over winter in an outhouse or fridge and then be brought back out in spring.
They can take 8months to 2 years to emerge

Moths when they emerge will need to be able to climb up the inside of cage to inflate its wings. Do not disturb during this time. After a few hours the males will begin to fly around in search of females. These need to be fed nectar and have pine needles in a stand for the female moth to lay her eggs on.
