Somewhere in another topic, I already wrote about the strange aggressiveness of Turkish stinging eardrums (compared to ours). The last trip only confirmed this. This was especially evident in the case of the Marmaris xylocopas, which are by no means similar in character to our peace-loving southern bumpkins.

Another example is the Turkish empuzas. I haven't seen any of the others yet, but I remember Fabre admiring their calm, maybe even phlegmatic, nature compared to real praying mantises, as well as their restrained diet. But they were French empuses. The Turkish ones did not show these traits in any way; quite the contrary, in terms of activity, the amount of food consumed and aggressiveness, they were in no way inferior to ordinary praying mantises or hyerodules.

Has anyone else observed a similar "character" difference between different species depending on the locality? What is the cause of this phenomenon and how much can it be objectively assessed?

Well, the reason for the phenomenon seems to be that the environment is different. The climate is different, the activity of organisms is higher - and the competition is higher, so the aggressiveness is high. I think it is possible to evaluate this objectively only by observations. At the same time, the observed species should be identical in different regions, not just genera. Xylocops and empusa are different, especially xylocops, they are very similar.

In general, an interesting question: differences in the behavior of insects in different parts of the range. I somehow did not notice such differences between Baku and Israel - but here the climate is quite similar.

As one of my friends says (referring to himself):: "Southerners, hot-boiled shelter, eh!"

Yes, climate plays a big role. And what was the aggressiveness of empuzas?

For example, in an immediate attack on a finger stuck in the cage smile.gif. Although, 1) it may well be from stress, 2) immediately after catching in the hand, they behaved very calmly, it seems, pretending to be a twig. Aggressive behavior showed itself already in the cage.
In general, other praying mantises that I saw live in the cage behaved much more calmly than empusas. These people were constantly banging on the lid, on the walls, just couldn't find a place for themselves. I got the impression that they were suffering from something like claustrophobia.

It may well be from hungerwink.gif, but in general, mantises often beat their paws on the outstretched finger, as if repelling. Empuzas are really more restless, they do not let up for a long time and try to get out of the jar, and then sit on the lid upside down.

I've had the same experience, but I don't think it's unusual. When how, depending on what comes across, usually males are more calm, even if you hit them, put flies in their jaws-but they are nothing, and females are more often aggressive (probably a maternal instinct), bite, attack, hiss like mad, eat well.. Even caught a female in our country - she was angry, caught a dead male in the Crimea-p.

Do they also hiss? eek.gif

He's probably talking about faith. Those on the defensive spread their wings and run their bellies over them , making a hissing sound. Females are really more aggressive, and they are also larger.

Yes, I'm talking about religion. Females love to do this, and the effect is amazing!

Yes, it looks impressive. Like this:

Long ago in my childhood I observed such a picture) forever in my memory remained... wink.gif

Yes, in our Far East, too, religiosa hissed like that. At first I didn't understand where the sound came from, but then I became interested and found out everything. I think it's just a defensive reaction. And the males are actually somewhat "softer" or something. This year, students brought me the larva of a praying mantis, too. I've never heard of mantises being bred in Tatarstan, but it's a fact. I only know that they exist in the Samara region, Ulyanovsk region, and a number of others. In this connection, the range boundaries may expand towards more severe conditions for heat-loving species?
