Potato Aphid - Macrosiphum euphorbiae

The adult wingless form is large 1.7 to 3.6mm and an elongated pear shape. It ranges from light green, yellowish green to pinkish red. It often has a darker stripe down the centre of its back, especially in immature nymphs. This species has noticeably long legs and two long tubes (siphunculi) at the rear end. The tail (cauda) is also long and finger shaped. The winged form has a much less distinct central stripe. The antennae and siphunculi are darker than in the wingless forms.

May be found on a wide variety of plants as it is highly polyphagous in the summer, feeding on over 200 plant species in more than 20 plant families.

May to September is the peak time although it may overwinter as an adult.

The winged forms are produced in May and June.

Thought to be fairly frequent and widespread in Britain.

Thought to be fairly frequent in Leicestershire and Rutland.
