Giant water bugs have been discovered in Cyprus, raising concerns among researchers and swimmers. These creatures, nicknamed "toe biters", belong to the Lethocerus genus and can grow to about 4.7 inches (12 centimeters) in length. Although these insects are usually found on the continent, their recent appearance on the island raises questions about how they arrived and their impact on the local ecosystem.

According to a study published in the "Grigore Antipa National Museum of Natural History Journal", researchers have observed an increase in reports of these bugs on the eastern coast of the island. Reports mainly come from swimmers surprised by the impressive size of these aquatic insects.
Giant water bugs, members of the Belostomatidae family, are formidable predators that feed on various aquatic prey, including fish and crustaceans. Their technique involves injecting digestive saliva into their prey to liquefy its content, a bite described as extremely painful, though non-toxic to humans.
Researchers are speculating on the reasons for the arrival of these insects on the island. They consider several scenarios, including possible migration induced by environmental factors such as winds or ocean currents, or a search for new food sources. However, no definitive conclusion has been drawn regarding the permanent establishment of these bugs in Cyprus.
Despite the concern raised by this new discovery, researchers believe that the island's ecosystems, similar to those on the continent, could limit the impact of these newcomers. Indeed, natural predators such as white storks and black kites are present in Cyprus and could contribute to the biological control of the water bug population.
As researchers seek to better understand the extent of this potential invasion, they encourage local residents and visitors to remain vigilant. Swimmers are advised to be cautious and avoid putting their feet in the water in areas where these bugs have been reported.
