A new threat has emerged in Europe as a species of enormous hornets, known as the southern giant hornet, has been spotted in Spain for the first time outside of tropical Asia. This discovery poses a threat to honeybees, humans, and other animals due to its ferocious predatory nature.
A New Threat to Honeybees and Other Animals?
A species of enormous hornets, known as the southern giant hornet (Vespa soror), has been spotted in Spain for the first time outside of tropical Asia. This discovery is “a little worrying” according to Phil Lester, an entomologist at the Victoria University of Wellington in New Zealand.
Characteristics and Threats
The southern giant hornet is a ferocious predator that can attack and eat creatures as large as geckos. It is one of the largest known hornets, with workers measuring over 3 centimeters long. Its introduction to Europe poses a threat to honeybees, humans, and other animals.
Possible Introduction Method
Researchers suspect that the hornets were introduced as hibernating stowaways in shipments to the region, similar to how yellow-legged and northern giant hornets were previously introduced far from their native habitats.
Concerns for Beekeeping Industry
Current Efforts
Sánchez and his team are now searching for colonies. Time may be of the essence while the population is still low, says Lester. “Now is the absolute time to get onto this and try and kill it.”

Even for humans, “this is an insect whose sting can be very painful and long-lasting,” says Sánchez.

The hornets’ genes and unmistakable alternating black, brown, and yellow coloration suggested they were southern giant hornets.
