Field notes and information

The taxonomic status of the anomalous blues in Spain is complex. This is how I understand the situation.

There are only 3 species in Spain. All taxa are variable and individuals of each one may or may not have a white line on the underside hindwing. In the north A. ripartii flies as subspecies A. ripartii ripartii and locally in northern Catalunya as A. ripartii agenjoi (formerly treated as a full species, the Agenjo's anomalous blue).

In central Spain, such as the Montes Universales, A fabressei.

In southeast Spain A. violetae flies.

Identification & Similar species: The three species described above are all extremely similar - location is the main aid to identification.

Distribution & Flight: Central Spain. Montes Universales (common, even abundant everywhere!) to Soria. Mid July/ early August.

Habitat & Behaviour: Dry grassy places with flowers.
