There are about 5,000 species in 6 subfamilies of spider wasp.

Most spider wasps are slender and black or dark blue, sometimes metallic.

Wasps have a three-segmented thorax. On spider wasps the third segment is solidly fused to its exoskeletal plate (pronotum) and to the middle segment, making them strong fliers; and the first segment is well developed, making them strong diggers.

Abdominal segments 1 and 2 are narrow.

The legs are long and spiny. The third segment (femur) of the hind leg often reaches past the end of the abdomen. The fourth segment (tibia) of the hind leg usually have a conspicuous spine at the end.

Most spider wasps have long wings.

Life Cycle

The female paralyzes one spider, drags it to her burrow, and lays just one egg. If the spider is large, a female will be produced. If it is small, the offspring will be a male.


Spider wasps are solitary.

This video is made in my backyard. While we were eating, an spiderwasp (Pompilidae) attacked a spider. In a few seconds he was paralyzed by the venomous sting. (This tragedy happened the first of August (2011).

After that i decided to follow the wasp and his prey to his hole.

The footage was shot using a iPhone 4.

  avispa versus araña ( Pompilidae)

Published on Jan 11, 2015

Filmado en Parque Finky el 10-01-2015. La avispa hembra captura, pica y paraliza a la araña, entonces arrastra a su presa de vuelta a su madriguera o a un nido especialmente preparado, donde un solo huevo se deposita en el abdomen de la araña, posteriormente bloquea la entrada dejandola atrapada. Cuando la larva de la avispa eclosiona, crea un pequeño agujero en el abdomen de la araña, para entrar en él, alimentándose vorazmente, evitando órganos vitales tanto tiempo como le sea posible para mantenerla viva. Después de varias semanas, la larva se convierte en pupa. Finalmente, se convierte en un adulto y emerge del abdomen de la araña.

No estoy muy seguro de las especies exactas, pero espero que con eso se den una idea.
El video fue tomado en el Jardín Botánico de la Universidad Tecnológica de Pereira, en Colombia.
Fantástico haberlo visto con todo detalle.

I looked at the UofM and the wasp is a type of Sphecid.



It is possible that it is a spider wasp. Which is a different classification than Sphecid.
Spider wasps comprise the family Pompilidae in the order Hymenoptera.
I am unsure about which one my wasp is, but am leaning towards Pompilidae,  as I cannot find a picture or description in the family Sphecid that fully describes the one I saw. There are 8000 known species, it turns out. But the photo of the spider wasp that I found is more like my photo in that it has very long hind legs, and is solid black with a hint of color to the wings.

Maybe somebody can help clear it up? I wish I had a better photo than my smart phone could provide. It was moving and hopping around rapidly as it was attempting to carry the spider off.
