Eupteryx decemnotata is a species native to the Mediterranean region, from where it spread to other European countries and even reached several states in the United States (Nickel & Holzinger, 2006; Rung et al., 2009; Rung et al., 2009; Ciafré & Barringer, 2017). It was first recorded in Argentina in the province of Mendoza (De Borbón et al., 2022) and later in Buenos Aires (Pereyra et al., 2025).
Like other typhlocybins, it feeds on the chloroplasts of leaf mesophyll cells, causing chlorotic spots on the leaves, known as stippling (Pollard, 1968). This species has been recorded as causing significant damage to aromatic ornamental plants in Tunisia (Chaieb et al., 2012) and to oregano crops in Turkey and Greece (Arslan et al., 2012). At high population densities, the damage intensifies and can eventually lead to the death of the host plant (Nickel and Holzinger 2006; Rung et al. 2009).
Regarding its biological parameters, laboratory studies indicate that the immature stage (from egg to adult) lasts approximately 29 days, with the fifth nymphal stage being the longest (Pereyra et al. 2025).
It is an oligophagous species that feeds on the mesophyll cells of plants belonging to the Lamiaceae family, such as lemon balm (Melissa officinalis L.), oregano (Origanum vulgare L.), lesser calamint (Calamintha nepeta Savi), rosemary (Rosmarinus officinalis L.), hyssop (Hyssopus officinalisL.), peppermint (Minthostachys mollis Griseb.), basil (Ocimum basilicum L.), thyme (Thymus vulgaris L.) and common sage (Salvia officinalis L.) (Mazzoni & Conti 2006, Nickel & Holzinger 2006, Lubiarz & Musik 2015).
