Painted bug belongs to the species

Painted bugs belong to the species Bagrada cruciferorum.
Bagrada hilaris is a species of shield bug known by the common names bagrada bug and painted bug. It could be mistaken for or erroneously referred to as harlequin bug.
The adult bug is 5 to 7 millimeters in length, shield-shaped, and black with white and orange markings. The female, which is larger than the male, lays up to 100 oval or barrel-shaped eggs on leaves or in the soil beneath plants.
The eggs are white when freshly deposited and turn orange over time. Within 8 days the first-instar nymph emerges. It is bright orange-red and turns darker as it develops, becoming black by the last instar.
