New records by citizen scientists in Turkey : 1 . Amasya : Merzifon , 25.VII.2017 ( Şeker 2017 ). 2 . Bolu : road to Avdan Village , 16.XI.2020 ( Okur, 2020 ). 3 . Kastamonu (centre), 14.VI.2016 ( Yaşayacak 2016 ). 4 . Zonguldak (centre), 14.X.2019 ( Aşar 2019 ) . FIGURE 5 . Perillus bioculatus (Fabricius, 1775) : A. Specimen from Amasya (photo: A. Şeker), B. Specimen from Kastamonu (photo: H. Yaşayacak). Comments : P. bioculatus is originally a Nearctic species ( Rabitsch 2008 ) and it was introduced to Algeria , Greece , Serbia and Turkey in Europe ( Aukema 2021 ). This alien insect was firstly reported from Tekirdağ in 1997 ( Kıvan 2004 ). However, the oldest material in Turkey was collected in Edirne in 1993 ( Fent & Aktaç 2007 ). Later, its distribution range expanded in the West and Central Black Sea and also Ankara in Central Anatolia ( Dursun & Fent 2018 ; Kıyak et al. 2019 ; this study). Probably it may appear in the provinces in between these regions. Therefore, additional observations are needed. Two of the new records were obtained in mid-summer (June, July) and the other two in autumn (October, November) ( Graph 5 ).
