Long-fingered bat

The Long-fingered bat (Myotis capaccinii) belongs to the order Chiroptera and the family Vespertilionidae. Contrary to misconceptions that it might be a plant pest, this species is a highly beneficial insectivore. It does not feed on crops but provides essential ecosystem services by consuming large quantities of insects.

Systematically, it is a specialized member of the Myotis genus. It is easily identified by its notably large feet, which are equipped with stiff, long hairs. This anatomical adaptation allows the bat to hover over water bodies and "trawl" for aquatic insects or those skimming the water's surface.

Regarding its biology and life cycle, Myotis capaccinii is highly dependent on aquatic habitats such as rivers, wetlands, and irrigation canals. They hibernate in caves during the winter, often in large colonies, where stable microclimatic conditions are crucial for their survival through the colder months.

The impact of this species on agriculture is strictly positive. By feeding on various nocturnal insects, including those that are common agricultural pests, they provide natural biological control. They are an integral part of the food web that keeps populations of flying pests in check within rural and agricultural settings.

Conservation measures are vital because this bat is considered a vulnerable species due to habitat loss and water pollution. To protect and encourage their presence, several strategies are recommended:

• Preserving wetlands and riparian vegetation to maintain insect populations.
• Avoiding the use of persistent insecticides that contaminate the aquatic food chain.
• Protecting cave systems from human disturbance during critical periods of hibernation and rearing.
