[Note Guidelines] Photographer's Note
Gasteruptiidae is one on the most easily recognised families of parasitic wasps. They are particularly distinctive because of their slender, subclavate metasoma, the dorsal articulation of the metasoma to the propodeum, the elongate, neck-like propleura, and expanded hind tibia.
The female of Gasteruption jaculator has a very long ovopositor with a white end.
The larvae of Gasteruptiidae are reported to be predators of various solitary bees and wasps.
One finds it on the ombelliferae in summer.
Gasteruption jaculator belongs to the super-family of the Evanioidea and not of the Ichneumonidae, which have longer antennas (at least 16 articles) and parasitize especially Lepidopterae.
--------------------------------------------------------
Le Gastéruption à javelot (Gasteruption jaculator) est une guêpe très particulière appartenant à la superfamille des Evanioidea.
Son gastre, long et fin, est attaché au sommet du propodeum. Au repos, ses ailes sont pliées le long du corps. La femelle a un très long ovopositeur (aussi long que le reste de l’insecte) avec une extrémité blanche.
On le trouve sur les ombellifères en été. La femelle dépose son oeuf dans l'habitat d'une abeille solitaire. La larve va alors dévorer la larve ou l'oeuf de l'abeille et se nourrir des réserves de pollen et de nectar entreposées.
Gasteruption jaculator appartient à la super-famille des Evanioidea et non des Ichneumonidae, qui ont des antennes plus longues (au moins 16 articles) et parasitent surtout des lépidoptères. Il se distingue aussi des Ichneumonidae
par un cou bien plus allongé, les tibias des pattes arrière renflés et le point de jonction de l'abdomen situé sur le sommet du thorax. (Wikipedia)

Hello Catherine,
A fine macro of this interesting-looking female parasitic wasp. The ovipositor is almost as long as of those that are parasitic on wood insects.
It is taken from a fine POV with excellent sharpness, DOF and contrast with the OOF BG, though a couple of much smaller wasps are also visible.
TFS,
Regards,
Ivan

Hello Catherine,

I like this close-up of the wasp. You have chosen a good composition with the slender body of the insect placed diagonaly in the image. As alois in your photos there is a nice soft light rendering such a reachness of color tones. You have found a good way to blend the color tones of the flower with the green and blurry background. Togehter with the sharpness of the insect gives to the image a nice depth.

Thank you for sharing,
Cristian
