Yellow Caterpillar

Observation - Yellow Caterpillar. Description: My son found this beauty on our willow tree in our garden, we found a similar spot here on ispot which helped us identify him... we thought you’d like to see ours too :) Does anyone know how long their larva gestation period lasts for?
