Sceliphron caementarium, also known as the yellow-legged mud-dauber wasp, black-and-yellow mud dauber (within the US), or black-waisted mud-dauber (outside of the US), is a species of sphecid wasp. There are some 30 other species of Sceliphron that occur throughout the world, though in appearance and habits they are quite similar to S ...
Although the tubes were never recovered from the ocean floor, the plane had been sitting on the tarmac for 25 days with uncovered pitot tubes. Investigators believe a black and yellow mud dauber, Sceliphron caementarium, got into the tube and built its cylindrical nest inside, causing faulty air-speed readings that were a large part of the crash.
Sceliphron, also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and build nests made of mud. Nests are frequently constructed in shaded niches, often just inside of windows or vent openings, and it may take a female only a day to construct a cell ...
Investigators believe that the most likely culprit was the black and yellow mud dauber (Sceliphron caementarium), a type of solitary sphecid wasp well known to Dominican pilots, which makes a cylindrical nest out of mud and tends to establish a nest in artificial, cylindrical structures. According to the final report, section 2.3 – "Aircraft ...
Females can build their own nests, but often refurbish nests abandoned by other wasps and bees, [4] particularly those of Sceliphron caementarium, [5] removing any spiders captured by S. caementarium and the larva, replacing it with an egg of its own and freshly caught spiders. [3] They go through multiple generations in a year. [2]
These six genera belong to the subfamily Sceliphrinae: Chalybion Dahlbom, 1843 i c g b (blue mud wasps); Dynatus Lepeletier de Saint Fargeau, 1845 i c g; Penepodium Menke in R. Bohart and Menke, 1976 i c g
Sceliphrinae: Sceliphron spirifex Sceliphrinae: Chalybion californicum Sphecinae: Sphex funerarius with prey A gold-marked thread-waisted wasp flying near blooming yellow ironweed. A Sphecidae wasp, probably Sceliphron caementarium, investigates two squash bugs, but doesn’t attempt capture to provision its nest.
Basically, S. caementarium was originally widespread in Central and North America, but has been introduced all over the place, including the "western Mediterranean" which could easily include Spain. There are, however, other, native, species of Sceliphron in Spain, such as Sceliphron destillatorium , which she might have seen instead.
