And did you know that...

... that a tiny humpback fly (Pseudacteon) attacks a fire ant (Solenopsis invicta) and lays eggs inside its body. After the larvae hatch from the eggs inside the ant's body, they secrete an enzyme that causes the ant's head to fall off. And in this dismembered head, the larva of the humpback fly continues to develop.

Fantastic! Thanks! By the way, at our university, humpback flies once bit the head of the department. And a well-known expert on them (humpback flies) wrote to me that this is a rather rare case of an attack of this species (Dorniphora cornuta) on humans.

As long as the head doesn't fall off. And then I personally was lucky in my life for managers bitten by a humpback...

In my case, the head definitely did not fall off, but the rest of the symptoms were obvious.

Dr. Niko, where did the photos come from?

yes photos are super! (I know how hard it is to take a picture of an insect in flight, and even such a crumb!)
by the way, do they only attack one species of ants?

Dr. Niko, where did the photos come from?

Yes, from the Internet photos. My God, can't anyone Google it?
Once a fire ant was brought to the United States from South America by accident. And the ant, s@ka, is evil. We thought about it and remembered that it has a natural enemy - the humpback. So the Americans are now posting dismembered ant corpses online.

And did you know, dear ones, that the mosquito-woodlouse from the genus Forcipomyia is able, according to some data, to make up to 1046 wing flaps per second, and according to others (see the article) - 2218 flaps per second!!!

Yes, I'm talking about the humpback (if it's a male). Such an impressive hypopygium for diptera is a rarity. If it's a female, it's a strange ovipositor, I've never seen one like it.

It appears to be a female with an ovipositor http://www.nysaes.cornell.edu/ent/biocontr...seudacteon.html

I'm sorry. Don't kick it too hard. Stybzili they photos probably with amerikosovsky site any. And who shot it, God only knows.

And here is the same ZH ishsho a lot of interesting things on gorbatki http://ivanov-petrov.livejournal.com/67863.html

Pea aphids are forced to live with pathogenic bacteria infected with viruses in order to escape from parasitic wasps that lay larvae in aphids, which then slowly eat insects from the inside, according to the authors of a study published in the journal Science.

Well, again riders were called wasps Now afidiid.

I mean, of course, not a banal example: bee dances are subject to certain laws, but something extraordinary.

I would not like to find fault, but the development of humpback is not at all" more extraordinary "than bee dances and is also subject to"certain laws".
I understood what was meant, but I'd have to be careful with the wording.

So tell us something about bee dancing.

Move it to the topic " Do you know what...".

So tell us something about bee dancing.

"Anything" is, of course, strong
There is a lot of information. At the same time, active research was conducted throughout the 20th century, starting with their discovery by von Frisch in the 20s and ending with the Michelsen robot in the 90s, which told the bees where to fly. And what intrigues and disputes there were! One of Frisch's fiercest rivals, Adrian Wenner, even published a separate book about it. There is still a lot to learn, and there is a lot of work coming out all the time. And you say "banal".

... that mantises hunt hummingbirds in Minnesota.

what do hummingbirds drink so red at?

thieves and cockroaches....

here's another good angle

Yes, today YaPovtsy burned in a terrible way ...

... that mantises hunt hummingbirds in Minnesota.

With all due respect, but... the lower photo seems staged to me.

Duck in the Americas-then mantises and birds do not disdain

With all due respect, but... the lower photo seems staged to me.

I'll join you. The situation is somewhat implausible.

in the last photo, the praying mantis really hangs strangely without catching on to anything with its legs, because it doesn't have suckers, and plastics are slippery

It is doubtful that a praying mantis would hold prey of this size.

It also follows from my little experience of keeping mantises that mantises are not inclined to attack such large prey relative to their own size.

And what will the keepers say? My experience of keeping praying mantises is not great.

It's not about weight, anyway. A mantis of this size is quite capable of holding a dead bird. But if she actively resists , then there are already doubts.

And I think it's true! that's it!

Hummingbirds are not very physically strong. The size of hummingbirds seems large because of their plumage. In fact, large mantises often attack prey larger and stronger than themselves, sometimes dying in the process. The first photo seems plausible - a praying mantis caught the bird by the head. In this case, the force of his front paws could easily break the hummingbird's neck vertebrae, which prevented further resistance of the victim. However, the courage of different types of praying mantises is not the same. So, female religios are usually very ferocious after mating. Males of this species, on the other hand, usually avoid large prey. Empuses almost never associate with strong prey. And the tree mantis is also a risky guy, regardless of gender. This American praying mantis is quite similar to religios and arboreal, so I would venture to assume that the facts in the first photos took place.

That's what I meant - hold and kill. Unlike the same spiders, mantises do not have the means to quickly kill prey.

On the other hand

[/q

The first compression force of captured prey is very strong in some mantises. Immediately after capturing the prey, the mantis hit it very hard a couple of times (I'll risk writing it with all my might) squeezes the front legs. Usually, this is enough to seriously damage the victim, if not kill him, and then he is practically incapable of force resistance. If you are not afraid to experience it, offer the mantis a grasshopper on your finger. If the praying mantis is large enough, you will feel a very sensitive pinch, even if the thorns will not be able to pierce the skin.
[/quote] Can't they? It depends on which one! In 1994, in Cyprus, I grabbed a rather large praying mantis with my hand. It didn't just puncture, but cut through the skin on my finger. Blood was pouring out of several holes at once.
