Craticulina

Genus of flies

Craticulina is a genus of true flies in the family Sarcophagidae. They are cleptoparasites of various species of sand wasps. They are ovoviviparous, laying larvae instead of eggs. The larvae share the prey of the sand wasp, and though they are much smaller than the wasps, many fly larvae may be present in each wasp larva, causing food to run short. Sometimes the fly larvae also attack the wasp larvae while they are small, especially if too many fly larvae and too little food are present.
