  • A Spangled-winged Thread-waisted Wasp (Ammophila pictipennis) places a larger pebble on its nest entrance to hide it from other insects. These wasps dig a brood tunnel and lay a single egg on a stung caterpillar. Then, before they leave to hunt for additional caterpillars (to ensure the larva has enough food until they pupate), they plug the brood chamber entrance with a larger pebble and hide it with the surrounding sand. Camouflaging the entrance prevents predation and parasitization of their larva by other insects. This image shows how it bends its front legs,  using the stronger hairs on them to move the sand quickly.

  • The subtle color variations of different plant fibers create a striped design as bald-faced hornets (Dolichovespula maculata) build up their nest. This wasp has a bolus of chewed pulp under its "chin" which it feeds through its mandibles, squeezing and forming it onto an existing paper edge.

  • A bald-faced hornet (Dolichovespula maculata) flying back to the nest with food - the abdomen of a Yellowjacket wasp.

  • German Yellowjacket (Vespula germanicaxanthic) building nest, in flight at nest entrance. Lower wasp is leaving with a clump of soil (excavating a larger underground chamber); upper one is returning with cellulose stripped from old wood (to build paper nest)

  • Chives (Allium schoenoprasum), flowerheads with feeding wasp.

  • A bald-faced hornet (Dolichovespula maculata) flys back to the nest; a larger queen wasp is at the entrance.

  • Eastern Yellowjackets (Vespula maculifrons) feeding on Cecropia (Hyalophora cecropia) caterpillar. One wasp has just arrived, the other is ready to fly back to the nest, with the bit of muscle already arranged for flight in it's mandibles.

  • An Eastern Yellowjacket (Vespula maculifrons) wasp feeding on a Cecropia moth (Hyalophora cecropia) caterpillar. This hornet has cut through the skin and is bitting off a manageable sized piece of the caterpillar’s muscular side to bring back to the larvae in it's underground nest.

  • A foraging Eastern Yellowjacket (Vespula maculifrons) approaching an injured Cecropia (Hyalophora cecropia) caterpillar that had been eating on lilac leaves. In my observations, the wasps left uninjured caterpillars alone. Biting Stable flys (Stomoxys calcitrans) often caused the initial damage, which weakened them and attracted the Yellowjackets.

  • Stable Fly (Stomoxys calcitrans) and Cecropia caterpillar (Hyalophora cecropia) it had bit. In my observations, the Stable Fly always did the initial damage, which then attracted the Yellowjackets. Undamaged caterpillars always fended off the wasps.
