Snail Killing Fly - Tetanocera elata

This is a family of small to medium sized flies. The members of this family deposit their eggs near snails. The larvae eat the snail. This means that the members of this family are useful in biological pest control. They are bred to reduce the number of snails in farming. But they are also the living proof of how complicated matters like these can become. The flies don't distinguish between noxious snails and slugs and useful ones. So what is a blessing for one branch of agriculture is a pest for the other, namely the farmers that breed edible snails. The females do not look for snails to lay the eggs on, they simply drop them on the ground. When the weather is favorable, which means quite wet, the larvae will hunt down the snails themselves.

Hallo Hans,
Wat een beest! Zijn naam is al net zo eng als hij er uit ziet. Erg mooie macro in bijzonder heldere kleuren en fantastische scherpte. Ik had er denk ik een verticale compositie van gemaakt. Er is wat veel loze ruimte links en rechts, maar de contrasterende kleuren in de achtergrond zijn prima.
Groet,
Peter

Hi MF Hans,

Exceptional capture of this very strange fly which i have never seen before. Love the focus and the blurr effect on its abdomen while thorax and head are so sharp. Very original capture MF!
TFS and have a nice night!
Cheers,

Hi Hans

Firstly, a very educative note on a species I have never seen or heard of before.
Thanks for the introduction. Once again TrekNature has done its part to inform
us of something very interesting. Not only those members who would still come
to see this, but also all the visitors from the broader Internet community.

The image is just great. Really top notch technical material. I don't know how
you managed to get that amount of DOF from the very shallow aperture at f/4,
but all that matters is the fact that even at this close range you made it work for
this shot. It resulted in excellent and sharp details. The bumped up colour saturation
is a feast on the eyes and the isolated and evenly coloured BG did a great job to
enhance the subject.

Very well done and TFS.
Regards
Loot

PS. After a bit of research, I found that this is the second posting of this insect on
TrekNature. So, unfortunately it missed out on my theme for "RARE or SIGNIFICANT
contributions to TN
". The first posting was done by Leslie Butler (Tetanocera Elata).

Hello Hans,
great portrait of a great fly. I have not seen this species before, must be a "First" on TN! How do you get at ID of flies? They are such a big and badly illustrated group. i added this picture to a list called "Dipterans of Europe-3".
Thanks a lot for this exceptional contribution.
Best regards
Dietrich
