Foxglove Aphid - Aphis armata

    Description

    The apterae of Aphis armata are black. Immatures often have discrete wax spots, but apterae rarely have such spots. The middle abdominal tergites in apterae are usually without dark sclerotic bands. The only reliable characteristic to differentiate the species from Aphis fabae is that the oviparae have hardly any swelling of the hind tibiae, whilst in Aphis fabae the oviparae have the hind tibiae strongly swollen. The body length of apterae is 2.2 to 2.9 mm.
