Dropping in to see how the Wasp family is doing at Audubon House at the Oslo Riverfront Conservation Area (ORCA). Pretty well, it looks like. The family is definitely growing larger as new members hatch out.
The Paper Wasp nest at Audubon House is coming along nicely with the development of multiple larvae in these images taken over the past week. Photos of two stages of development. The image at left shows an early larval stage with a more developed stage at right. The developing larvae chambers are given large caps under which the young wasps pupate then emerge from as adults.
A warm day marks a return to activity around the Paper Wasp nest at Audubon House. Note above the wasp at left that there is a developing larval wasp in the chamber. Something to focus on for the next visit. The three wasps making up this small nest will soon have help – and most likely a bigger nest soon enough.
Two images from of the activity around the Paper Wasp nest at Audubon House from Saturday. The wasps seemed a bit somnolent in reaction to the chilly and rainy day with none of them venturing out from their cozy cover and out into the bad weather. Lucky for them, warmer days are ahead.
A gallery of images as a follow-up to yesterday’s post about the Paper Wasps nesting at Audubon House. First, a close-up of one of the wasps working on the nest. The architecture of the open cells of the nest each with their single egg is clearly visible in this shot. The eggs hatch after two to three weeks and if you look closely at the wasps at lower left and right, they are regurgitating thoroughly chewed insects into the cells […]
Paper Wasps (Polistes spp.) at Audubon House work on a nursery for their young. Note the single eggs in the open chambers. The wasp at top is working downward to expand the nest, while the wasp down below puts the finishing touches on the egg chambers in the interior of the nest. Paper Wasps feed on plant nectar and help pollinate plants. They also prey on insects, especially caterpillars, to feed to their young. Paper Wasps get their name from […]
