Many insects make cocoons when they are young to protect themselves from the big, bad world, full of predators (and cable news channels). Ichneumon wasps have a found a way to make this process ...

Wasps are notorious for devouring other creatures from the inside out. Now scientists have learned that after they’ve killed something, they wrap themselves up in its cocoon for good measure and ...

Then, they exposed all three groups of cocoons to green lacewings, an insect predator that loves to chow down on vulnerable wasp larvae.

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

SPIDEY SENSE A parasitic wasp larva forces a spider, shown here at 50 times normal speed, to change its prey-catching web into a stronger, simpler structure that can support a cocoon for the larva.

The cocoon caps of several paper wasp species, relatives of some you may see in your yard, fluoresce yellow-green under ultraviolet light and lend the whole nest a groovy glow.

A wasp larva injects a spider with a web-altering drug, driving the spider to spin a shelter just right for a wasp cocoon.

During this time, the wasp larva performs whip-like twitches against the interior of the cocoon causing the entire structure to move approximately five centimeters at a time.

What a way to go. The larvae migrated outside the hornworm and are currently in the rice-shaped cocoons metamorphosing into adult wasps. These beneficial wasps are good guys.

By hijacking a spider’s nervous system, a wasp larva can manipulate the spider into making a stronger web, according to a study published yesterday in The Journal of Experimental Biology. Of ...

While trekking through the tropical forests of northern Vietnam, scientists unexpectedly discovered wasp nests that glow fluorescent green under ultraviolet light.
