A presentation on bats and moths followed by a bat walk is being organised by Heritage Malta on September 12 at 7.30pm.

Those attending the walk will be able to hear different species of bats by means of a bat detector and visit a moth trapping site to see different species of moths attracted to a source of UV light.

The moths will be identified and immediately released in the same area from where they were captured.

Heritage Malta said that there will be no moon on September 12 making it ideal for the observation of these two groups of nocturnal creatures.

Bats fly at night and find their way by echolocation. They send high-pitched noises which cannot be heard by humans and use the echo from their surroundings to find their way around and to detect flying insects. A bat detector would be used to locate and identify bats. This apparatus detects the sounds made by bats and converts them into sounds which can be heard by humans.

Moths would be studied using a moth trap. This consists of an ultraviolet lamp placed in front of a white background. The ultraviolet rays attracts moths, trapping them for study before release.

Tickets at €12 for adults and €10 for seniors, students, Heritage Malta members and children under 12, are available from all Heritage Malta sites and museums and online.
