The canary big-eared bat (Latin Plecotus teneriffae Barrett-Hamilton, (1907)) belongs to the class of mammals and is nocturnal. It hides during the day in volcanic tubes, caves, old water galleries, abandoned buildings and other dark and cool places.
This mid-sized (over 44 mm) member of the Vespertilionida family can be found mainly in areas of mixed pine and woody masses, with preference given to Laurisilva's Fayal Heath areas. This bat feeds on various insect species; including numerous butterflies, moths and night moths. After hibernation, they mate in the summer, usually in September.
