The yellow-legged mud dauber is a wasp that builds nests from mud balls and fills each cell with paralysed spiders for its young. It is found across North and Central America and the West Indies, and it has spread to many other parts of the world. Its stings are rare because it is usually gentle and tends to keep to itself.1

Leef in

Canada, United States, Central America and the West Indies; introduced to Pacific Islands, Peru and parts of Europe and the Mediterranean1

Noord-Amerika

Tuis

It lives in a wide range of places, including rock ledges, man-made structures, puddles and water edges, cypress domes, longleaf pine and turkey oak areas. Its nests are often found in shaded spots sheltered from the weather, such as under bridges, inside barns, in garages, on open-air porches and under house eaves.1

Lengte

2,4 cm tot 2,8 cm (0,9 in tot 1,1 in)1

Topspoed

omtrent 31 km/h (19 mph)

Vlieënd, rowwe skatting

Wat eet dit?

The female hunts spiders, stings them to paralyse them and stores them in the nest as food for her larva. Adults feed on nectar at flowers, especially Queen Anne's lace, parsnips and water parsnips in mid-summer.1

Hoe om dit te herken

Black abdomen with yellow markings on the thorax1
Yellow legs with black trochanters and femurs1
Black eyes and black antennae with yellow scapes1
Tawny wings1
Body length of about 24 to 28 mm; the population in the desert southwest often has a yellow petiole1

Word dikwels verwar met: There are 33 other Sceliphron species around the world that look and behave much like this one. Within the United States, it is the only species in its genus with yellow-marked legs, which is the main way to tell it apart there.1

Gifkrag

Steke

Gif kom deur 'n angel uit.

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

Stings are rare because the wasps are solitary and usually nonaggressive. The species has a low reproductive rate.1

As dit steek

Skraap 'n byangel uit en koel die plek af.
As die persoon sukkel om asem te haal, die gesig of keel swel, of hy voel flou, is dit 'n allergiese noodgeval: bel jou noodnommer en gebruik sy adrenalienpen (outo-inspuiter) as hy een het.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

die moeite werd om te weet

Feite

A completed nest can be as large as an average human fist, built from many mud cells stacked vertically.1

A common cuckoo wasp, Chrysis angolensis, often steals food from Sceliphron nests as a kleptoparasite.1

After finishing a series of cells, the female leaves and never returns to the nest.1

Adults are often seen feeding on nectar at flowers in mid-summer.1

Mite-breker

Mite: Mud dauber wasps are aggressive and likely to sting people.

Waarheid: They are solitary and usually nonaggressive, so stings are rare.1
