Common Blue Mud-Dauber Wasps

Dear Susan,
We believe these are Common Blue Mud-Dauber Wasps,Chalybion californicum, which are pictured on BugGuide.  According to BugGuide:  “A large, active, blue-black wasp with irridescent blue wings. Frequents flowers for nectar and buildings for nest sites.” and “Females construct mud nests in sheltered areas, often under the eaves of buildings, and provision them with spiders.”  We suspect they are searching for mud near your deck for nest building.

Great Golden Digger Wasp

Dear Vinny,
This is a Great Golden Digger Wasp and Daniel has been posting images of this species from his Los Angeles garden last month where they were nectaring from blooming onions.  The Great Golden Digger Wasp is a solitary wasp and they are not generally aggressive and they do not defend their nests.  The female feeds on nectar and milkweed is a marvelous nectar producing plant.  The female also hunts Katydids which she stings and paralyzes and then drags back to her nest where she lays an egg that will hatch into a helpless larva that will eat the paralyzed Katydid alive.  Great Golden Digger Wasps rarely sting humans, but the sting is likely quite painful.  She will only sting if threatened.  She would much rather save her venom for paralyzing Katydids than warding off predators, so she has aposomatic warning coloration (orange and black) and she moves in a jerky and attention getting manner to warn would be predators to avoid trying to eat or lest they encounter a painful sting to the mouth.

Thank you Daniel. This information will ease our minds in regards to potential bites as they are appearing in large numbers.

Yellow Legged Mud Dauber

Dear Hope,
This is a Yellow Legged Mud Dauber or Black and Yellow Mud Dauber, Sceliphron caementarium, which is pictured on BugGuide.  This is a solitary wasp and solitary wasps rarely pose a stinging threat.  Social Wasps will often sting to protect the nest, but solitary wasps do not protect the nest.  The Yellow Legged Mud Dauber builds a nest from mud and is often seen near mud puddles.  According to BugGuide:  “nest is provisioned withNests are provisioned with spiders”.

Your letter to the bugman:  I was out in my pollinator garden this afternoon and noticed a huge Great Black Wasp on the mountain mint.  A very exciting discovery as I rarely see them.  And then, I started noticing that there were maybe a half dozen of them in the garden! I am hopeful that this means a colony is getting established somewhere on our property.  I already have a nice colony of Great Golden Diggers, so have Black Wasps would be a bonus.  A few photos below.

Great Black Wasp

Dear Deborah,
Your Great Black Wasp images are awesome.  That is exciting to learn you may have a stable population of this incredible predator in your vicinity.  Daniel sees Great Golden Digger Wasps every summer on onion flowers and chives flowers, and there is a healthy population of Katydids in the garden as well, but last year was the first time he had a Great Black Wasp sighting on a wild sunflower, but alas, he had no camera handy.
