Biology and notes. Copestylum azurea  is associated with sclerophyllous forests in the Mediterranean basin of Central Chile. Although this species does not meet the VU classification under the IUCN for EOO subcriterion, its distribution has been affected by land-use change by urbanization and croplands, especially avocado crops, disappearing from several historical localities. These localities are included in this catalog, but in the official local Ministry of Environment red list, these are not considered. Therefore, this species has been classified as VU in the 13 th process of classification of species by the Environmental Ministry of Chile under the IUCN criteria (www. mma.gob.cl/clasificacionespecies). After six years of citizen science project, recently this species was seen alive in precordillera of Santiago feeding on Colletia hystrix Clos  (David Bijman, CSP record) and representing the first record in situ of C. azureum  .

Conservation status. VU under B2ab (iii) using AOO = 124 km 2 and only five historical localities (or subpopulations) remain (originally these were 27); EOO = 22,724 km 2.
