When I took the cover off my picnic table's sun umbrella I found a number of these structures running down one of the folds (see Photo, left).They look like they are made of dried mud and inside each one is a vivid yellow powder and a single thin, curled-up larva. Each structure was about 5 centimetres long.What did it, how did it do it, how long did it take - and should I get rid of them?Ian Gilbert, Monks Eleigh, Suffolk, UK
Those would be the egg chambers of the mud dauber wasp. http://www.google.com/search?q=mud+dauberIf you don't mess with the adults, they're harmless. As the chambers you found have been compromised, the wasp larva will most likely die. There would be no further harm if they are simply discarded.
Bees and Wasps are far MORE BENEFICIAL than they are harmful.They pollenate plants and eat plants pests that damage a variety of garden plants we humans enjoy for their beauty or for food.So to "get rid of it" without knowing what it is as about as close to idiotic and ignorant as one can get on a minor matter.I wouldn't be surprised if it weren't some sort of preditory wasp that worked hard to capture various caterpillars and other garden pests to stock the larder of her little egg case made of mud.To repay her hard work ridding your garden of nasty plant eating pests by destroying her brood is pretty cold and utterly stupid. Rather than git rid of it, if it is still intact, and embryos growing, I'd monitor it and see what does emerge.To kill something without knowing what it is is one of the biggest reasons why we have done so much damage to our planet and so many animals are close to extinction.If we should get rid of anything it's the type of caveman thinking that makes us want to kill anything we are not familiar with, and "scooping it off and getting rid of it" would very likely kill the entire brood.
Smash it, destroy!! We are CAVEMAN!!!I would boil it with egs... or maybe put in microwave, film it for youtube while watching the poor little innocent larvas pop like popcorn! ;)But hey I'm just a caveman!
Obviously the above post trying it's damndest to be uncontroversial.I would imagine that just be inadvertently disturbing it may already have killed them. As to the above post rallying about hatching them, I see your point about the hard work done by the parent, however, get a life, its bugs. Admittedly vitally important, have some perspective.
