Comments: The species is very frequent on the island, extending north up to Valparaíso. Also present in Argentina (González 2006, 2019).

Summary: The Coccinellidae fauna of Isla de Chiloé is composed by 18 species, 17 of them are native and the other one, exotic. This is consistent with the richness of the respective mainland territories (the adjacent province Llanquihue has 15 species). The presence of two endemic species on the island is remarkable considering that similar sized mainland provinces (Llanquihue, Osorno; Palena, etc.) do not have them. Among the native species, 12 of them are characteristic of the Valdivian forest. The presence of Harmonia axyridis is a threat to the native Coccinellidae on the island ( Grez et al. 2016; Roy et al. 2016).
