The localities in Bulgaria where the species has been recorded are in the town of Malko Tarnovo, near the Turkish border, while the locality in Türkiye is in the Asiatic part of Istanbul. Data on the current distribution range in Europe, a list of plants on which A. conica has been found, and photos of the species are provided. © 2023 Sciendo.

The species overwinters at the egg stage and has two generations per year. The number of host plants identified in this study is 57 (belonging to 31 families). With previous studies, the number of host plant species in Türkiye has reached 58. The main host plants were Ligustrum lucidum W. T. Aiton and Olea europaea L. Eggs are laid in double rows in the thin twigs of shrubs or trees of one-year old, exceptionally in the main vein on the lower leaf surface of Magnolia grandiflora L. The mean number of eggs laid on L. lucidum and O. europaea were 31.88 and 21.80, respectively. Mean length of egg masses was 17.90 and 15.36 mm and mean twig thickness was 2.21 and 2.20 mm, respectively, on L. lucidum and O. europaea. Zelus renardii (Hemiptera: Reduviidae) was identified as a predator of P. shantungensis. © 2023 Bulgarian Academy of Sciences. All rights reserved.
