Sceliphron caementarium in LA County – part 2

I sent pictures of the black and yellow mud dauber recently, and then discovered the mud daubed nest – mud huts? – for the larvae – at least I think so since these were on the inside of my garage door and the wasp was captured in my house. Now the connection is clear. I have never seen this carefully constructed wasp nest before so thought this might be a nice addition for identifying this wasp being in the vicinity. The nest was too high for me to put a comparison measure in the picture, but the tubes are about 1.5-2 inches in length and about 1/3-1/5 inch in diameter. The tubes are sealed in these pictures. About a week later, the doors were clearly open and tubes empty. When my gardener removed them, he broke open the mud and they were nearly hollow with only one dessimated carcass of a spider at the very end of one tube. Fascinating!

Potter Wasp

Hi John,
This is one of the Potter Wasps in the subfamily Eumeninae, and we believe we have correctly identified it as
Eumenes fraternus based on images posted to BugGuide.  Potter Wasps are solitary wasps that build small mud nests provisioned with caterpillars that look like miniature ceramic urns or vases.

Cool Green Spider

I noticed our hummingbirds weren’t using this particular feeder and then I saw why. This big yellowjacket killing spider took up residence underneath it. I took this picture and relocated the spider. Do you know what kind of spider it is?

Green Lynx eats Yellow Jacket

Hi Jeff,
Your spider is known as a Green Lynx, and it is a hunting spider that does not use a web to snare prey.  Green Lynx Spiders are often found on blossoms where they wait for pollinating insects, and we are amused that it had taken up residence on this nectar substitute.  We don’t believe the Green Lynx would prevent the hummingbirds from visiting the feeder.  Yellow Jackets can be ornery, and it is our theory that if the Yellow Jackets frequent the feeder, they may be keeping the hummingbirds away.

Wasps!
Location: Abbotsford, British Columbia

I was trimming the plants around that area and I happened to touch the lilac tree without seeing this basketball size nest very well camouflaged among the leaves. I got stung by two bees!It literally knocked me on my butt. I was lucky I discovered the nest the following day! It took the welt on my arm 3 weeks to heal. The nest is visible because my husband had a trimming pole and cut some branches away.
What sort of wasps are these? Very aggressive!

Bald Faced Hornet Nest

Hi again Frenchie,
This is the nest of Bald Faced Hornets, and while they are not considered aggressive, they do defend the nest.  We posted another image of a Bald Faced Hornet Nest early early this morning after returning from work.  They seem to like lilac bark for nest building material.  They chew the bark to produce a papery substance.

Great Golden Digger Wasp

Hi Ed,
This is a Great Golden Digger Wasp and it is our favorite wasp.  You need not worry about her hole.  She is a solitary Thread Waist Wasp, and she shuns her own kind unlike other “solitary” wasps like the Cicada Killer that nests in colonies despite having her own brood.  Great Golden Digger Wasps prey upon Katydids.
What state are you in anyway? We found a Delaware County in Ohio, Indiana and Pennsylvania and we aren’t certain that Indiana Co Rd is in Indiana.

Bald faced hornet grubs

I’ve been watching these grubs fall from the hornets nest all morning. The adults pick them up and fly away with them. Are they next year’s queens?

Hornet Nest

Hi Laura,
We hope our readers know that they can just click on all photos posted after 2009 and get enlargements in a new window.  It is a nice feature of our site when it comes to making the information we have to convey even more accessible.  We must confess that we don’t know why the larvae are fleeing the nest and the workers are flying away with them.  Perhaps the hive is overpopulated and they are culling the grubs.  They may instinctively know how to select the most perfect and fecund of the brood while it is still larviform.  They may be choosing their heir because the entire nest is basically the mother.
We love your photo.  We hope to have some free time in the next month to be able to research the phenomenon it communicates.
