notes
outside of the Mediterranean region, where the primary host plants does not occur, the species lives continuously on grass roots, associated with the ant Tetramorium caespitum. The louse exhibits two forms. The first one feeds on grass roots and produces honeydew upon which the ants feed in turn. The second one resembles an ant larva and produces corresponding signal compounds, and feeds carnivorously upon the ants’ brood (Salazar ao, 3015a)
