| The Mediterranean fruit fly, commonly called the medfly, is one of the world's most destructive agricultural pests. |
|
| After apparently being eradicated by 1930, the medfly was spotted again in 1956 in Miami. |
|
| The female wasp lays her eggs inside the developing medfly egg. |
|
| A young wasp grows inside the medfly, eventually killing it. |
|
| It was a medfly, a threat to a billion-dollar fruit industry. |
