A few weevils:

The fees were collected during practical training for 2nd-year students of the Saratov State Agrarian University named after N. I. Vavilov (SSAU). Methods of fishing were manual harvesting and mowing with a stream, which was carried out along roadsides, dry valleys and from the territory of a mixed grass meadow. It should be noted that mowing was also carried out on alfalfa and sweet clover kuligs and partially on dry bogs overgrown with feather grass.

I apologize for the quality of the photo

1. presumably Sitona humeralis
2. presumably Sitona sp.
3-4. presumably Sitona puncticollis

the beetle crawled on my arm, in length-2-3 mm.
thank you in advance

13.02.2010 12:56, vasiliy-feoktistov

Some kind of leatherworm (Dermestidae).

13.02.2010 16:11, megamega

there don't seem to be any provisions or skins in the bedroom.
what can he eat?

It feeds on dust... which accumulates in various hidden places.
this is Attagenus smirnovi. very frequent guest of city apartments.
there is practically no harm from it.

If it's dust, it's even a good thing, especially if it doesn't spit out dust mites...

If only with dust (this bastard also eats the collection). I found such people at home for this "black case"

for people who do not have insect collections in the house, of course harmless

! But the creature eats collectible material very effectively!

I don't agree. In Tachyerges salicis, firstly, the bandages on the elytra are thinner and of different colors: the back is much lighter, almost white. Here, compare:

Dear "buggers",

please tell us:
picture: IMG_2823.jpg

15.02.2010 22:57, Cerambyx

2823-Buprestis strigosa or haemorrhoidalis (or maybe rustica)
2825-Buprestis novemmaculata
2828 - Oxythyrea funesta
2830 - the same
2832 - I would say Hylecoetus dermestoides
2834 - Calopus serraticornis
2841 - Calosoma denticolle
2843 - Carabus ?canaliculatus
2847-Calosoma investigator
2849 - same investigator
2851 - Carabus schoenherri
2853-Carabus ?convexus
2856 - Carabus convexus
2858 - Cychrus caraboides

I don't know cows very well, previously -
2837-Harmonia quadripunctata
2839 - Hippodamia notata

2834-Adalia decempunctata, yes or Harmonia quadripunctata-Andrey is right, judging by the head and pronotum, Harmonia quadripunctata is more likely
2839 - Hippodamia is probably notata, but something is confusing - I think Hippodamia septemmaculata

the latter is Harpalus sp.

Dear "buggers", please tell us:

My opinion on goldfish:
2823) Buprestis haemorrhoidalis Herbst, 1780
2825) Buprestis strigosa Gebler, 1830 (pronotum without border)
Now I especially can't participate (the network "lags" terribly), but this is a question for my provider. So sorry

Then I'm afraid I may not be able to decide at all - from the photo I would say that this is some kind of Sphodristocarabus, and they are best just by the labels differ...

Alexey, is this Hippodamia notata??
picture: Р8020039а.јрд

although the DV determinant lists the genus Semiadalia, what is the correct name for this species now? Hippodamia seems to be characterized by the absence of femoral lines, but in this one they are very developed. Thank You

17.02.2010 18:24, Алексей Сажнев

Yes, I think the ladybug Semiadalia notata (Laich., 1781), so it's more correct to call it, you're right)

Beetle sem. Prostomidae, two species for Russia (In Russia - 2 centuries). Source of assessment: A. G. Kireychuk [1995] from the ZIN website). Prostomis mandibularis (Fabricius, 1801) is found in Europe. On Sakhalin, Prostomis mordax Reitter, 1889 (this is exactly how the distribution is written in the English source Øst-Asia, bl.a. Sakhalin), so I think it is:
Prostomis mandibularis (Fabricius, 1801)
