The interactions between spider hosts and parasitoid wasps constitute a remarkable example of co‐evolution, where intricate behavioural and physiological modifications underpin the survival strategies ...

Parasitoid larvae that feed within caterpillars that eat cabbage plants influence the plant via the caterpillar, making the cabbage plant an unattractive prospect for moths looking for a spot to lay ...

A new species of parasitoid wasp that constructs remarkable star-shaped cocoon masses is reported from the biodiversity hot spot Ryukyu Islands. Researchers observed how the wasps construct 'stars' ...

In the uninfected condition, a Drosophila larva contains adult precursor tissues called the imaginal discs (such as those for the wings, eyes, legs, etc) inside its body. The fly larva undergoes ...

A light crackling sound floats above a field in northern Switzerland in late summer. Its source is invisible, tucked inside a dead, dried plant stem: a dozen larval mason bees striking the inner walls ...

A research group from the Biodiversity Unit of the University of Turku studies the diversity of parasitoid insects around the world. Parasitoid wasps (Hymenoptera) are one of the most species rich ...

A tiny parasitoid wasp from Asia has established itself in the Netherlands without deliberate release. Field research by ...

To provide their offspring with plenty of food as they grow, parasitic wasps lay eggs inside other animals. After they hatch, the larvae eat their way out and kill the host in the process, though ...

The solitary parasitoid wasp lays her egg in the body of a caterpillar or similar host. After it hatches, the developing larva dines on the caterpillar’s insides until eventually tearing its way ...

A curious team of researchers from the University of British Columbia was purportedly studying Anelosimus eximius spider nests in Ecuador in an effort to learn more about the different types of ...

Riddle us this: Is the video above fascinating or disgusting? Trick question. It’s both. The awesome/repulsive footage—which shows a parasitoid cotesia urabae wasp larva exiting its caterpillar host’s ...
