Aphid and Ant
Panaphis juglandis (Goeze, 1778) is an aphid that lives on the upper sides of leaves of Walnut trees Juglans regia, in rows along the central veins.
The photo. shows nymphs - they feed on the walnut sap, and excrete drops of so-called honeydew. Ants commonly feed on the honeydew deposited on the leaves, but sometimes also attend the nymphs to 'milk' them directly, stimulating them to produce the honeydew and then consuming it, as these photos. show. The nymph is about 3mm long.
