Tiny 'Mosquito Terminator' Spider Found Near Lake Victoria

In the ecologically rich region surrounding Lake Victoria, straddling Kenya and Uganda, scientists have identified a remarkable creature: a minuscule jumping spider, measuring just five millimeters, with an extraordinary dietary preference. Dubbed the 'mosquito terminator,' this spider, scientifically known as Evarcha culicivora, exhibits a singular focus on mosquitoes that have recently fed on human blood. This unique characteristic, coupled with its attraction to human scent, sets it apart in the arachnid world.

Reč je o terminatoru komaraca (Evarcha culicivora), malenom pauku dugačkom oko pet milimetara.

Belonging to the vast Salticidae family, known for their exceptional vision and stealthy hunting techniques, these tiny predators are not merely survivors; they are specialized hunters. Their diet is not indiscriminate; given a choice, they overwhelmingly select mosquitoes that have already consumed a blood meal. This isn't just about sustenance; it's deeply intertwined with their reproductive success. The scent acquired after feeding on blood is crucial for attracting mates, making their specialized diet a key element in their survival and propagation.

Poput Arnolda Švarcenegera u čuvenom filmu Terminator, i ovi mali predatori imaju misiju da pronađu i unište svoju metu – u njihovom slučaju, to su komarci.

The significance of Evarcha culicivora extends beyond its fascinating biology. In a region heavily burdened by mosquito-borne diseases like malaria, which claim hundreds of thousands of lives annually, these spiders emerge as an unexpected ally. Mosquitoes, particularly the Anopheles species responsible for malaria transmission, are known for their attraction to humans – their breath and the scent of our feet. Intriguingly, these spiders share this anthropophilic trait, often found near human dwellings and seemingly drawn to the same cues as their prey. Their presence offers a glimmer of hope in the ongoing battle against these devastating diseases, showcasing nature's intricate and often surprising solutions.

Ako im se ponudi izbor između komarca koji nosi krv i bilo kog drugog insekta, pa čak i komarca koji nije sisao krv, u devet od deset slučajeva izabraće onog sa krvavim obrokom.
