Bad Den, I'll postpone a few takes. Fortunately, almost all species are collected in more than one copy.
I have my own method of settlement,take the aquarium, take the land, and populate with red earth ants, then, after a while, take red forest (straw) ants and settle on top, destroying the first new ones will quickly master the buildings of the first ones and you will have a colony of red ones in the aquarium!It's simple!

I see a lot of ribbon bars during the day, but only a few fly up to the lamp.As far as I remember (I read somewhere), they almost never fly up to the lamp, they land at a distance.
I don't know what color the egg laying is in softlings, but the larva lives in the litter, so the egg laying should be there And the Colorado potato beetle has orange-colored eggs on the underside of potato leaves.

Indeed, according to our classification, Lybethiadae (snouts) and Ridionidae (or Erycinidae???) - different families. But I don't know why.
Dear colleagues, tell us who has experience of fishing with the help of canopies, what is your opinion. Is it worth starting up? Yes, and I would like to be more precise about their device, in terms of carvings, designs, etc. I want to try it out this season.
Trofim, dichloroethane is not just harmful, it is toxic. I would recommend something less vigorous, at least the same ethyl acetate.
in glasses, you can also add meat at the very least.. But the best bait is beer with wine and sugar.. If you can't smuggle anything, then I think you can buy beer there at least, add a little sugar, maybe yeast, a drop of salt and pour it into glasses. You need to take a net! Without a net, you can miss a lot or not catch anything at all, at least from what will fly!
1. And how to remove ordinary cockroaches.2. Why don't they start up in apartments?3. You say that they are practically harmless, but I read somewhere that they carry up to 40 infectious agents.The list of pathogens carried by cockroaches is really "indoctrinate..." But they are contaminants, i.e. if there is no focus of infection in the vicinity (tuberculosis hospital/homeless shelter), then ...
An idea! You can bend her legs in the right shape, body, and all that at the next molt! Such beauty will turn out! This post was edited by RippeR - 05/30/2007 23: 41

You either need to make a plan or put labels, and in any case, you need to choose memorable objects..
I've heard that male sailboats have a larger inner notch on the second pair of wings than females. True, I didn't check it myself.

This rocking and stickmen many svoestvenno. Apparently this insect also mows under a green branch in the wind. Really, her diet is quite different.
There is information that gotchas are multi-layered in Barabash Levada and Kedrovaya Padi.And we ate trepang.
I used to catch Omofrons, Elafruses, and maaki Carabiners in this way. I hope that you will also have good results, but you need to check the traps every day, so that they don't flood.This post was edited by Dinusik - 05/21/2007 12: 05

So I'm wondering how you can distinguish spini from pavonia from the trap. The latter type is not particularly rare, although we do not have it.
Question about Dorcadion elegans. [attachmentid()=20549]The area of distribution of this species is mainly the Lower Volga region and adjacent steppes of Kazakhstan. As far as I know, Plavilshchikov very conditionally drew the western border of its distribution in the east of Ukraine (Luhansk and Donetsk regions), which, I quote: "does not reach far to the Dnieper". The discovery of D. elegans in ...
