What's Nesting in the Bird House???

What’s Nesting in the Bird House???

Dear Toni,
We are presuming that you attached two images of a bird house because the creature in question has nested inside the bird house.  Your letter did not describe the creature, which you have stated is a Bee.  The Orchid Bee,
Euglossa dilemma, is a bright green bee that is often seen hovering near blossoms.  If the Bee you have had for over a year is not bright green, it is not the Orchid Bee.  We have received another report of Green Orchid Bees nesting in an abandoned birdhouse, but Bumble Bees will also nest in a birdhouse.  Only the female Orchid Bee builds the nest, so you should use the pronoun “she” when referring to your creature.

I found these today in the slots in my window were my screen would go. I only have half screens so the top never has anything in it.

Nest of a Grass Carrying Wasp

Nest of a Grass Carrying Wasp

Dear Angela,
We believe this is the nest of a Grass Carrying Wasp in the genus
Isodontia.  According to BugGuide:  “Females make nests in a tree, hollow stem or other cavity, divide into sections and close with grass. They provision with Orthoptera (Tettigoniidae, Gryllidae)” and “These wasps commonly make their nest in the narrow track found above outer windows.”  We cannot tell if the nest in your photo has been provisioned with Crickets.  The female Grass Carrying Wasp paralyzes the cricket which remains immobile, but alive, as the wasp larva feeds upon it.

When in the spring/summer is best to clean out old grass carrying wasp nests allowing them to emerge as happy, healthy adults?
Signature: Dee Maack

Nice question Dee.  This is speculation on our part.  Based on information on Grass Carrying Wasps that is available on BugGuide:  “Taken from the Internet Reference below (Penn State): The adult wasps emerge from their cocoons in early summer, mate, and the females locate a suitable nest site. She collects blades of grass and grass and hay stems to line the nest cavity. The wasp can be seen flying through the air with the blades trailing beneath her. She lands at the hole and enters, pulling the blade in behind her. After the nest is prepared, she hunts for tree crickets (i.e., Oecanthus sp.), captures and paralyses them with her sting, and transports them to the nest. She deposits eggs in the nest and the emerging larvae will feed on the living, but immobile crickets. When the larvae reach the appropriate size (in 4–6 days at 70–75° F.), they spin a cocoon and pupate. The adult wasps emerge in 2–3 weeks. In Pennsylvania, Isodontia mexicana typically produce two generations per year.”  We would suggest mid to late June as a time to consider clearing out nests from the previous year, however, if you notice pupae as you are cleaning out the windows, you may want to delay the clearance a few more weeks.  We have added your question to a recent posting on the nests of Grass Carrying Wasps.

Hi Bugman! My 9 -year old daughter spotted this this morning, it’s larger than a football and very well made. Can you please tell me what we are dealing with here? We have three small children.

Hornets Nest

Hornets Nest

Dear Mamacyn,
This is indeed a Hornets Nest, and it most likely belongs to Bald Faced Hornets.  Since it is October and the first freeze of the year is not long off, we wouldn’t advise you to take any action as the colony will die with the coming winter.  Hornets do not reuse a nest.  The mated queens will hibernate and begin building new colonies in new locations in the spring.  Hornets are generally not aggressive unless the nest is threatened, so this nest was probably active the entire summer and its inhabitants were content to cohabitate with you and your family to neither species’ detriment.

Thank you Daniel!  I will advise everyone to keep away until we know that they have abandoned the nest.  I’d love to keep it, it’s so pretty.
Thank you again!!
Take care,
Cynthia

Hi!
I love your site and have used it many times to identify insects that I have found. It is very helpful!
In July I came across this very neatly folded piece of grass (?) on the shoreline of an island in Georgian Bay, Ontario, Canada. I’m wondering what could be hiding inside. Would it be some kind of caterpillar, or a spider? I was very impressed with the tidiness of the folds and seams. So far my internet searches haven’t worked out, so if you have any ideas of what created this, I would appreciate knowing.
Thanks,
Kristin

What’s That Nest???

Hi Kristin,
We believe this is most likely the shelter of an Orthopteran, a group that includes Crickets.  We recall reading once that there is an Orthopteran that fashions a shelter out of grass, but we cannot find the source of that information at this time.  Perhaps one of our readers will be able to assist.

Hi Daniel,
Thanks for your thoughts – now I’m a step closer!

Update from Kristin:  10 September 2013
Hi Daniel,
I did some more research (Google image searches for “insect+grass+nest, etc) and came across this blog post. It looks like the Leaf-curling Spider nest that this person found is pretty similar to the one I spotted. If I spot another one next summer, maybe I’ll cut it open and see for sure – I just didn’t want to disturb whoever was inside.

Hi Kristin,
Thanks for getting back to us.  It reminded us that Eric Eaton wrote back and we forgot to post or to notify you.
Congratulations for finding the information on your own.  We found a images on The Home Bug Garden of a Leaf Curling Spider Nest and the spider is in the genus
Clubiona.

On September 4, Eric Eaton wrote back, but we forgot to post.
Daniel:
I would strongly suspect a spider in this case, but I can’t be certain.  Doubtful it is a Carolina Leafrolling Cricket, as they usually select trees.
Eric

Hi Daniel,
Thanks for the update. What cool things spiders can make!

I found this bee nesting in a crack of my window and foolishly killed it thinking it was going to sting me. I pulled out the dead bee and its little leaf nest and decided to look it up online and found out it is either a mason bee or a leaf cutter bee. I live in Phoenix, AZ and I could not find any pictures of native leaf cutter bees that looked liked this one. The closest ones I found were species from Africa or the Middle East.
Could you please tell me if that is what this is?

Leaf-Cutter Bee and Nest

Leaf-Cutter Bee and Nest

Hi Daniel,
We are more generalists here at What’s That Bug? than we are specificists when it comes to identifications.  We aren’t qualified to take this Leaf-Cutter Bee in the family Megachilidae to the species level.  Your photo is a nice documentation of the adult imago, larva and nest.  Leaf-Cutter Bees frequently nest in sash windows.  We are sad you were frightened of the bee and ended its life and we hope you will be more tolerant in the future.  Leaf-Cutter Bees are not aggressive.

We found these under a wood deck. Somewhat similar to ’earth’/mud nests made by wasps, but I am pretty sure that yellowjacket wasps are not what made these. They are about 1” long.

Dear shreddly phreddly,
We agree that this is a Wasp Nest, but it is not a Yellowjacket Nest.  Yellowjackets are social wasps that build a paper nest.  The mud nest builders are solitary wasps.  Wasps in several different families construct nests of mud that are provisioned with food for the developing larvae.  Breaking one of the cells to view the contents might help to identify the nest builder more specifically.

thanks!  yeah, we were sorta freaktout when we turned the deck over and saw that assemblage (a dozen, i think).  It did look somewhat like something out of a science fixion or horror movie!
