Lady beetle egg mass (and leafhopper) - day before hatch - Harmonia axyridis

Lady beetle egg mass (and leafhopper) - day before hatch - Harmonia axyridis
Philadelphia County, Pennsylvania, USA
June 24, 2009
Size: 1.4-1.5 mm long
The circled egg was later dislodged from the leaf. I kept it separate from the rest of the egg mass and photographed the larva that emerged every day, providing a complete record of the larval instars of a single individual.

I don't know what species the leafhopper nymph is. Many of these flightless early instars were on the tree, and the eggs were probably laid there to take advantage of the food source.

Plant: Maple, Acer sp. The tree was a small, bushy sapling, under 5 feet (1.6 m) tall.
