Why would a woodcutter beetle have such a long and heavy mustache?

Especially in some species.

The whisker pattern is the same as that of male moths. To find a female. You may have noticed that male barbels have longer whiskers than females.

Thanks Beetle. Unfortunately, I don't know the principle, but you can already see it somewhere.
Interestingly, and this is also a naive question, is there an inverse correlation between whisker length and population density in certain species?

By the way, Cerambyx cerdo turns over with the help of whiskers if it falls on its back - I've seen it many times.

I was somewhat surprised to read from N. N. Plavilshchikov (1936, p. 2) that the most reliable family of woodcutters differs from this one. leaf beetles by the ability of the former to "throw their antennae behind their backs" while leaf beetles only go forward.

Bolivar:
it looks like the same thing as with neocidalis.. Where have you seen so many of them? I've never found anything other than 1 leftovers.. Where are they hiding, how to get them?

I've seen it in the Krasnodar Territory 20 times in my life. Even somehow I did not consider it rare

, for example, at night on the trunks of poplars. You go with a flashlight - they are sitting at the bottom. Even in pairs. And I saw larvae in the dust, presumably his.

Andrey and Cerdo fly dozens of times under streetlights during the season in the Caucasus... task sort only integers and larger

ones

02.08.2007 14:38, RippeR

This is the Caucasus. I have 2 problems with it: 1) Not to get me to the Caucasus in the near future, well, in any way.. Maybe next year, but the probability still remains well, too small

2) I already have the Caucasian subspecies cerdo, thanks to Frantik. But our nominative is not present

02.08.2007 17:32, Mikhail F. Bagaturov

It's clear. We mowed them down together for a couple of years

By the way you're not the only one who has a problem with the nominative

It's actually much less common and wasn't really available before, as far as I remember.

02.08.2007 22:36, RippeR

So I have just from the French pair, what you have nakosili

03.08.2007 13:56, Mikhail F. Bagaturov

I already understand, Andrey.
Therefore, catch the nominative

05.08.2007 21:41, RippeR

it is necessary to have a cottage and catch the light all year round we have nominatives

beetle, you as always

hawk moth lay their eggs

and about the sawyere...everything seems to be clear here...the larger the surface of the whiskers, the greater the number of sensillae that can be placed on them....and females, as a rule, do not need sensilli so much...so their sawyers are shorter...
dear beetle, sensillae are not just for finding females! consult AB!

13.08.2007 13:09, amara

Thanks to fly-km for the clarification.
To put it bluntly, I didn't ask why insects need whiskers at all (although it wouldn't hurt me to know that either),
but why this family has such highly developed whiskers (compared to other beetles).

there are always exceptions...

I think, because they may have poorly developed other sense organs, and orientiatya somehow need to ...
wed and what are the plate sawyers

what surface...!

13.08.2007 14:38, vilgeforce

If you remember the exceptions, you need to remember spondyl still-also the mustache is short.

And the plates have a large whisker surface, maybe due to the search for food/substrate for feeding larvae? But because of the need to dig this substrate, another engineering decision was made: the long mustache when digging, probably, is easy to break. Spondylitis, as far as I remember, develops in the roots of pine and has just a short mustache.

13.08.2007 16:58, amara

... yes, and in other families there are "barbels" as for example. Uleiota planata from flatwoods. And this, by the way, does not prevent living under the bark.

if you go into wood, then with a long mustache is not very easy, amara! although most adults do not climb there

and in general...the plates have a much larger surface as a result..but this is my opinion...and sawyers probably think differently...

It may very well be that this has developed as well as the antlers of a deer - that is, a secondary sexual trait, even in my opinion they use their whiskers as a deterrent - as I saw one mustache, krtspny, 5 - 6 centimeters on its peregdny legs, stand up, move its whiskers and creak at the sight of one young cat that is around it I didn't know what to do with it.

yes, with a mustache, the view is more spectacular...... in a deer, they serve for everything....

21.08.2007 13:24, fly-km

the theme goes out, apparently.....

I just read in Naturl History (N3 / 2008) that the species Onychocerus albitarsis (native to Peru) has a scorpion-shaped stinger at the end of each tendril, and two ducts on it, one of which had traces of an unknown substance, possibly poison. The researcher who took this beetle received a sting that felt like a bee sting.
Thus, it is the first stinging beetle discovered in the world.

Another question, probably also a child's question, about the long beetle whiskers - how are they located during the beetle's flight: straight ahead, spread out to the sides, or thrown on its back? Thank you.

Straight ahead and spread apart.

I read it, didn't believe it, scored in Google, the first result is here:
http://www.springerlink.com/content/2021660xh5565131/
so it's probably true...
