Biology and notes. Platycheirus fenestratus is, together with P. chalconotus, common in several habitats along Chile. Platycheirus fenestratus occurs in native shrublands, croplands and forests (Medan & D’ambrogio 1998; Medan & Arce 1999; Contreras 2012; Smith-Ramírez et al. 2005, 2016). Larvae are considered important in the biological control of Sternorrhyncha (Thompson et al., 2010, López-García & Maza 2013). Adults have been recorded visiting flowers of Aristolochia chilensis (Porter, 1921); native blueberry Aristotelia chilensis (Molina) Stuntz (Contreras, 2012); T. quinquenervia (Medan & D’Ambrogio, 1998; Medan & Arce 1999); Embothrium coccineum J.R. Forst. & G. Forst. (Contreras, 2012); E. cordifolia Cav. (Smith-Ramírez et al. 2005, 2016); M. domestica (Vanessa Durán & Rodrigo Barahona-Segovia, pers. obs.) and Ugni molinae Tucrsz (Neira et al. 2003). Platycheirus fenestratus is also one of the most common species visiting urban trees as well as exotic flowers in private gardens and parks (R. Barahona-Segovia et al. unpublished data).
Conservation status. LC; EOO = 952,271 km 2; AOO = 100 km 2, 23 subpopulations and 24 localities.
