Abstract: The egg and fifth instar immature of the jumping plant-louse Bactericera lyrata
Seljak, Malenovský & Lauterer, 2008 (Hemiptera: Psylloidea: Triozidae) are
described and illustrated for the first time based on material collected in
Slovenia and reared on Potentilla reptans (Rosaceae) which is confirmed as a
host plant. The morphology of the fifth instar immature is compared with closely
related species and a key for the identification of the fifth instar immatures
of west Palaearctic species of Bactericera Puton, 1876 associated with Rosaceae
is provided. Bactericera lyrata has three generations per year in Slovenia with
adults overwintering. It is unknown whether they migrate to conifers. The colour
dimorphism of adults of the summer and overwintering generations is illustrated
and briefly discussed.
