A recent study has revealed the discovery of a new species of wasp that exhibits a unique reproductive behavior. This species of wasp lays its eggs inside adult fruit flies, and the larva develops within the fly’s body. When it is ready to emerge, the wasp larva tears open the fly, marking a gruesome but fascinating phenomenon.
The adult wasp, known as Syntretus perlmani, is found in various locations across the eastern United States. For this study, researchers collected specimens from Mississippi, Alabama and North Carolina.
Matthew Ballinger, a contributor for FOX Weather, shared his insights on the current state of weather conditions.
The female wasp, smaller than the tip of a pencil, infects a larger fruit fly by stabbing it in the abdomen with a specialized organ. Through this organ, she injects an egg into the insect’s body.

Scientists conducting the study observed a fascinating behavior in a host fly. They noted that the fly seemed to be aware of the wasp’s attempt to deposit her egg and actively tried to defend itself.

“Drosophila serve as hosts to the first-known parasitoid wasp that preys on adult flies,” according to a study published in the journal Nature. The authors of the study granted permission to FOX Weather to share this information.
During the course of approximately 18 days, the egg undergoes growth while the fly maintains a relatively active state.
According to researcher Logan D. Moore, the wasp larva possibly benefits from its fly host’s ability to continue obtaining food resources throughout the nearly three-week infection, as reported by FOX Weather.
The fly persists in coexisting with the growing wasp egg inside its body, but it experiences a decline in nutrient levels and a decrease in certain bodily functions due to the presence of the egg.
A fruit fly is hosting the growth of a wasp larva inside its body. Matthew Ballinger from FOX Weather reports that the storm is expected to intensify over the next few days.
“One of the authors of the study, Scott Richard Shaw, explained that the behavior of the fly is altered as a result of being infected by the larva of this parasitic wasp, which ultimately reduces its ability to reproduce successfully.”
As the wasp larva grows inside the fruit fly, its reproductive abilities decline. Eventually, it emerges by tearing through the fruit fly.
In the insect world, there are numerous instances of parasitic species that primarily prey on young insects. Therefore, the finding of S. perlmani stands out.
Shaw expressed his astonishment at the uniqueness of this case, pointing out that the recently discovered wasp targets the adult stage of a fly. This remarkable finding marks the first instance of such behavior ever recorded.
According to Shaw, the wasps specifically target the adult stage of the fly. This suggests that they are likely to be active during the same time period as the flies.
During the spring and summer months in the northern U.S., the wasps are more inclined to lay their eggs in fruit flies. However, in the South, this behavior may occur throughout the year. Matthew Ballinger from FOX Weather reports on the latest weather conditions.
Scientists argue that despite the unsettling nature of the wasp’s approach, it can actually have a positive impact on the ecosystem by helping to control the fruit fly population.
According to Shaw, the significance of wasps as natural control agents and their economic importance in controlling insect pests without the use of chemicals cannot be overstated.
