So many nice images that Jorge has, I'm a little envious .crex said: Did you see any more hunting activities or were they just humping around? Today I saw one male catching a little dipteran, as it happened  . I will tell you how it happened:I was watching the male hybotid, who was on an eucalyptus leaf and, as little creatures strolled by he reacted to them, following them with his eyes. When a small dipteran passed in front of him he focused on it and attached when the prey turned its back on him  . It was amazing to see.Jorge Almeida said: smiley precisely. he didn't care anything about the "MANY" bounces he had. smiley this is what I call "hard sex". smiley I also saw the "soft sex"  . Even though the female carried the male, it wasn't really soft (you will find out what I mean when I send a video to Jorge ).   |

I notice that in the video where the male is mounted, he is also quite rigid - he doesn't appear to be using his front and rear legs to cling on, they are just stiffly outstretched. In the predation video, the frantic action of the back legs reminds me of the madly wagging tails of lambs when they feed. Fascinating stuff - well done you two. Susan |

Yes, the male never moved during the whole mating. But I wonder why the female caused all that agitation . Maybe to increase the chances of fertilization? |

On the last Wednesday (09/04/2008) I found several Tachydromia. Today this dead female has that strange white structure on the tip of the abdomen. What is it? Eggs? A parasite? |

If they are not dried out yet, please, do so.

Today I finally saw the beginning of a mating of Tachydromia. I've decided to fallow a male to see if I found anything new. After a few minutes, I saw him catching a small dipteran, and some more later a female approached and mating began at an amazing speed. I wasn't even able to tell who made the first move . When I finally made sense of what was going on, the female was feeding off the male's prey (did the male give it voluntarily, or did the female stole it?).Unfortunately I couldn't manage to film the scene, it was too quick  . 1- male feeding before the mating  2- mating (female with prey) Another intresting thing happened before the mating. While the male was feeding, a spider tried to attack him. As a response, the male repeatedly lifted his abdomen trying to intimidate his opponent, and succeeded . I only got to take one sloppy photo of this behaviour. 3- defensive behaviour  4- during the hottest part of the day, a female takes cover from the heat thanks to the vegetation . |

Today I started to look for Tachydromia at around 8 AM, until 6 PM. I only found 3 specimens. The adults are disappearing. I found 2 females and 1 male, all of them in the afternoon. After several hours searching for specimens without success, I finally found the last two almost simultaneously at around 5.40 PM. Why is it? Chance? |
