FOund in the Burnt Lands on Cypress Spurge. You can see how the colour varies between this one and the previous image. The moths were introduced as a bio-control agent for the non-native Leafy Spurge (Euphorbia esula) which is a serious invasive of crop fields. The caterpillars are known to feed on the spurge. However, they also feed on Cypress spurge, another non-native species, and in some cases, leave the leafy spurge in favour of the other.
