European hornet

Scientific name: Vespa crabro

Size: 25-35 mm

Origin: Europe, Asia and North America

Name (ES): Avispón europeo

Description:

Detected in the Balearic Islands in 2022.

The European hornet is not a native species to the Balearic Islands. Although its invasive potential in the Balearics is unknown, it is being targeted as a cautionary measure. It seriously affects beekeeping activities given its preference for feeding on honeybees. Hunting pressure can lead to bees ceasing all gathering activities and thus represents a danger to their survival.

Scientific name: Cydalima perspectalis

Redness: 40-45 mm

Origin: Eastern Asia, Japan, China, Korea

Name (ES): Polilla del boj

Description:

Present in the Balearic Islands since 2018

As its name suggests, the boxwood caterpillar feeds on the boxwood, specifically its leaves. Partial or total defoliation of the hosts may represent a danger for plant survival. The Balearic Islands are home to two species of this plant: Buxus sempervirens and B. balearica, both endemic species to the Balearic Islands and classified for special protection.
