Hi Bugman!
I live in Boquete, Panama and found this nest in the tree outside my house. I know that insects are fun and interesting, but the sight of this nest gives me the creeps. Can you tell me what kind of creature builds such a nest and feels that they can hang out by my porch like they own the place?

Hi Cate,
This appears to be a Hornet Nest, but we cannot make out individual insects well enough in your image to provide an exact identification.

Hi Rick,
Thank you for sending this image of what is most likely a queen Bald Faced Hornet beginning to construct her nest.

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

Subject: Maybe a Borer?
Location: Coryell County, Texas

This visitor flew off within moments of landing, so I wasn’t able to get a really good photo, sorry. Is it a Borer, perhaps the Black Locust Borer? I looked this insect up on Bug Guide and your website, and I found the Locust Borer on your website from September 10, 2013.
According to notes I read, the male have longer antennae than the females, so this may be a male?
Its colors were alarming, and I didn’t actually want to get too close, although it’s probably harmless to humans, if not to trees. Its wasp mimicry worked on me!
Would this explain the buzzing-wing sounds and sawdust found near our oak firewood? We’ve tried to spot the buzzing-sound -and-sawdust-maker, but whatever it is, it’s a crafty insect and good at hiding.
Thanks!

Locust Borer

Locust Borer

Hi Ellen,
While we don’t know what is buzzing and creating sawdust around the oak logs, you are correct that this is a Locust Borer,
Megacyllene robiniae, a species that appears in the autumn.  The adults are fond of goldenrod.  They are excellent mimics of stinging Yellowjackets and males do have longer antennae.

Hello again. I realize that I should be working and will have to make up this time later this evening, ha!, but I remembered that I had written about the buzzing from the woodpile and sawdust before. I found that post: Locust Borer On October 2, 2013 · Category: Longhorn Beetles
The locust borer was not the insect creating sawdust, so I went back to the oak firewood just now and sure enough, more sawdust. I turned the log above the sawdust over, and found our Carpenter Bee, hard at work. The log has several tunnels carved into it by the industrious bees. I’ll attach some photos. In one, you can see her (?) abdomen as she busily kicks out sawdust. She paid absolutely no attention to me whatsoever. Another photo shows the entire piece of wood, and one shows the empty tunnel entrance after she had kicked out sawdust and climbed all the way back into the tunnel to chew some more. I wonder if the long tunnel to the right of the working bee had housed larvae before? It had some sort of substance in part of it, that looked like old sawdust, perhaps, or pollen?
I also discovered and photographed a beautiful little moth that was trying hard to look like a lichen, and succeeding very well. It can be seen at the lower left part of the log.
After taking the photos, I turned the wood back over and placed it where it had been before.
So, now I suppose we should locate the woodpile farther away from the house, given the bees’ prodigious wood-chewing abilities, and I’ll see about repainting the trim on the house soon to discourage any house-chewing, and I wonder if I’ll need to check for tunnels in the wood before burning firewood next winter? Would hate to be a home wrecker!
Thanks again! Love your site, except for folks’ parasite questions but that’s part of life, too, I guess.
How you answer so diplomatically I’ll never know, but I always learn something or have a bit of a laugh when I visit What’s That Bug.
Best wishes,
