UNITED NEWS INTERNATIONAL (UNI) — Our world is home to an insect that uses its spine to saw its way out of a host.
Scientists described the new species in a report published Jan. 30 in the Biodiversity Data Journal.
It’s a type of wasp from Costa Rica. It’s about the size of a sesame seed and lays its eggs inside the body of other insects.
When the larva hatch, they eat the host from the inside until they mature into adults.
Other similar parasitic wasps will, at this point, chew their way out of their host but scientists think this new species uses ridges on its back to saw its way out.
Once free to fly away, it likely looks for a mate, then lays eggs in a new host, starting the cycle all over.
The wasp may have a grisly life, but scientists say they don’t harm humans and actually help keep pest populations in check.
