Hi I took this image today, 25th August 2006, in Silgueiros - Viseu - PORTUGAL. I put a pitfall that caught some very interesting insects and spiders. Spiders belongs to the Gnaphosidae family. (all 4) 1 - Thrips sp. ??? 2 - Wasp --- which family? it is wingless 3 - acari ?? 4 - Collembolans jorgemotalmeida attached the following image:  [193.77Kb] |

cthirion wrote: 4" not 1"= thrips! 3= mite in english (acarien) Yes, it is mite. Sure. But the 4 I think I have almost 99% sure that is collembolan. It is very different from Thrips sp. Edited by jorgemotalmeida on 26-08-2006 15:36 |

I think Jorge is right about 4 not being Thrips but Collembola. Jan Willem |

On this photograph, number 4 has parts of different density on the body, the collemboles are more uniform in their structure............... but here it is very small, I am not sure! ? ?Strong dish for collemboles! ? cthirion |

You see, not zone of shade on all the body! ? ?At the thrips, one sees the wings lying on the back! ? ?on your photograph, one sees zones of shade! ? ?But as long as I would not have a specimen seen under the magnifying glass........! ?

Brian - I think this has got to be the best shot of a predatory mite in action I have ever seen. I raise my pooter to you!

Thanks Tony- I didn't realise these were predatory- thought it was just an opportunist, I have a few mmore shots of it as well . Jan yes think it is a bark louse it's eating. Brian V. |

Yes, the Bdellidae are important mite predators. One species has been used in Tasmania for control of the "Lucerne Flea" - a destructive collembollan. Your photo shows the silk threads with which these mites tie down their prey before feeding. An astonishing photo, reminiscent of some of the early screenshots from "Half-life" - (you may need to ask a gaming geek for an explanation - show them the image, and they'll know what I mean!)
