   Forgive the illiterate: Astrabad - where is it?

Cryptorhynchidius lopathi L. - Moscow

Like Cr. l a pathi ?

And yet it is necessary so: Cryptorrhynchidius

urgent how to distinguish a female from a male Rhynchites bacchus (L.).
by length and attachment of antennae can?
On the left is a female and on the right is a male?or the same thing

I think by the relative length of the head tube ("proboscis"). In my opinion, you are right: on the left - the female, on the right-the male.

Do females have a longer "trunk"?

I would say both the trunk and the place of attachment of the antennae in females in a different way (I'm not a specialist. by rinhids)Just from 45 pieces (caught by mowing a net on plums, thorns, apple trees,apricots), you can clearly see the differences, probably between males and females?
For example, the female Tatianaerhynchites aequatus (Linnaeus, 1767) has a much longer trunk

In the book about pests, it is written that they differ in the hairs on the abdomen (on the underside), that the female has yellow hairs...But I already have them all on the dies.

That's right, again about the question of dies. Aesthetics clearly goes against the information content: on the die - it is undoubtedly beautiful (you have a sticker that borders on a work of art in general), but gluing a small thing from the side to the triangle is more practical for later determining the mounted copies. And those that are bigger, pinned - and order! Then twist and turn, look anywhere.

Well, I almost disagree with you!
Firstly, for me, gluing everything in a row on a triangle does not save time,but to make an outrage out of an insect
to prick means to break through (to spoil an insect with a through hole)
Well, look, you need to turn it in advance before gluing it on the die

I understand it was necessary to look at everyone under the bottom, and then stick.looking at hairs is not a problem for those who have binoculars at hand

Well, I think everyone does it in their own way, as they are accustomed (to mount the material)
I met with one entomologist who generally collects on mattresses

Carefully pasted on a triangle and straightened beetle looks no less aesthetically pleasing than on a rectangular die (in fact, only the shape of the die changes).

it depends on what and how to glue.. Do you also glue very small beetles? And then there is nothing left for the ardent opponents of the sticker..

what is it all about then?.
