On this page you can find photos submitted by users. If possible, the species are identified by the kerbtier.de ID team. Sometimes determination by photo only is impossible, in this case at least a hint on family and genus and potential species will be given.
Requests to the kerbtier.de ID team can be submitted on the request page. The answered requests are published here shortly (currently 4 hours on average) after submitting.

Request: Maia (Porto), Portugal
1st: 06.10.2013
2nd: 04.06.2014
Size: about 10-11 mm
NOTE: i even don't know if it is the same specie
Species, family:
Entiminae sp.
Curculionidae
Comment: Hi Carlos, here I have to check it later - I don't even know the genus of the top of my head. It is a species out of the subfamiliy Entiminae. Best regards, Thomas

Request: At Maia (Porto), Portugal
2013/NOV/03
On a wall, but near the forest; about ~5-6mm
Species, family:
Donus sp.
Curculionidae
Comment: Hi Carlos, this is a female of the genus Donus, from the weevil tribe Hypericini. There are many species in Portugal and a determination would be possible only by examination of the specimen itself under a binocular microscope. But it has a nice and dark coloration for a Donus species. Best regards Thomas

Request: In Maia (Porto), Portugal
2014/ABR/15
On Ericaceae Erica sp.; very small, about 3mm
Species, family:
Micrelus sp.
Curculionidae
Comment: Hi Carlos, this should be a representative of genus Micrelus. Two species are present in Portugal: M. ericae, which lives on Erica and which fits your pictures. And M. ferrugatus. I've never seen a specimen of this species. Literature says it is polyphagous, which I can't neither conform nor refute. I better put Micrelus sp. here. Best regards, Christoph

on Genista sp. (FABACEAE)
NOTE: is it CHRYSOMELIDAE Gonioctena olivacea??
Species, family:
Gonioctena cf. olivacea
Chrysomelidae
Comment: Hi Carlos, yes, this should be Gonioctena olivacea. As we're not experts for the Portuguese fauna, I put a cf. to it, to signal some residual uncertainty. Best regards, Christoph

Denmark
2014-09-11
Request: This Staphylinidae was found in the southern part of Sjælland in Denmark 11th of september last year (2014). Is it possible to narrow down to species or at least genus? Maybe Omalium? Habitat was deciduous forest floor.
Species, family:
Omaliinae sp.
Staphylinidae
Comment: Hi Brianwillum, since all our admins have seen this request including our Staphylinidae expert Thomas and did not comment, I have to leave it unresolved. Should be subfamily Omaliinae, but we cant determine the beetle any further. Sorry & best regards, Christoph

small; about~4mm
On Agapanthus sp.
NOTE: i thought it would be Anthonomus rubi ..but i don't think so.
Thanks for this one and all the that i request.
Species, family:
Ceutorhynchus sp.
Curculionidae
Comment: Hi Carlos, this is a member of genus Ceutorhynchus. There is a number of blueish species occuring in Centraleurope which are not easy to identify and I'm afraid there will be a few more in Portugal. So no way to identify down to species Level. Best regards, Klaas

Comment: Moin Käfer mit dem Rüssel, da können wir ihn getrost belassen. T. starkii wäre mir ja lieber gewesen, aber die Wahrscheinlichkeit ist recht gering. Viele Grüße, Klaas Hier geht es leider zurück zu Tetrops sp. da inzwischen eine weitere Art, Tetrops gilvipes adlbaueri Lazarev, 2012, hinzugetreten ist, die nur am Genital unterschieden werden kann. LG, Christoph

Request: Noch mehr fröhliches Rüsselraten mit gestochen scharfen Fotos :-D. Hier ist das ganz kleine Käferchen nochmal: Es gibt leider nur Foto A und B, und das hier ist jeweils die Originalauflösung. Foto C ist noch einmal das Bild zusammen mit dem Oedemera dingsbums, zum Größenvergleich. Funddaten: Straßenrand an Feldern bei Frechen, 59m üNN, am 14.05.2014. Ich bin gespannt!!!

Apionidae sp.
Apionidae
Comment: Hallo Rüsselkäferin, das ist wirklich nicht zu machen. Hier kann man nur raten. Wenn man mir die Pistole auf die Brust setzen würde, würde ich Ceratapion onopordi raten, ener der häufigsten mit blauen Elytren, und da passt die Gestalt ganz gut. Den wohl häufigsten blauen, Perapion violaceum kann man wegen der Rüsselform ausschließen. Viele Grüße, Michael

Request: Hi.Pleas ID Curculionidae,probably Dorytomus cf. dejeani.24.1.2015-Southeastern Slovakia,cca 5mm,under bark of Salicaceae (Populus sp.)
Species, family:
Dorytomus dejeani
Curculionidae
Comment: Hi mario, confirmed as Dorytomus dejeani. The similar D. taeniatus would be a little smaller, would display a little bit lower contrast, and would almost exclusively be found on willow. Best regards, Michael

Request: Diese kleine Käfersammlung habe ich im Urfttal abgelichtet, einige der etwa 4-5mm langen Tierchen saßen im Gestrüpp am Waldrand, auf 439m üNN. Gefunden am 06.06.2014. Phyllobius roboretanus? Fotos A und B zeigen denselben Käfer, Foto C sind zwei andere Exemplare auf derselben Pflanze. Hoffe, es passt. Lieben Gruß!
Species, family:
Phyllobius roboretanus
Curculionidae
Comment: Hallo Rüsselkäferin, entweder Phyllobius roboretanus oder Phyllobius viridiaeris. Beide sehr schlecht zu unterscheiden. Aufgrund des sehr stark gerundeten Halsschildseitenrandes tendiere ich zu roboretanus. Da sollte aber noch eine Zweitmeinung her. lg gernot Ich stimme zu. Viele Grüße, Michael

Country, date (discovery):
Belgium
2015-01-11
Request: Heverlee, Belgium, 11.01.2015, in detritus on the flood line of inundated forest area. Additional pictures to #20743, commented by Michael. That specimen was cleaned (left one) and two additional specimen are added, and shot under oblique illumination so a short keel at the base of the pronotum is clearly visible now! The specimen at the right showed a deep narrow cut in the middle of the anale sternite, so I presumed this was a male. I tried to pull out the retracted anal segment to make it fully visible, but messed it up. :-( I definitely need more practice to handle these <2mm beetles, and to make crispy pictures of such tiny details.
Given the presence of the pronotal keel, it cannot be E. laeviusculus? Is E. ruficapillus again an option? I found an Euaesthetini key by Volker 1994, but the pronotal depressions are confusing. Thanks for additional comments!
Species, family:
Euaesthetus ruficapillus
Staphylinidae
Comment: Hi Johan, excellent work, the keel at the base of the pronotum now unequivocally identifies them as Euaesthetus ruficapillus. I think pronotal depressions are quite variable. Sculpture (punctation) of the pronotum is a better character, but without specimens from different species for comparison, not so easy to judge. A good character is the last sternite of the male (the shape of the incision you noticed). Best keys can be found in the new vol.4 of Freude Harde Lohse, which is not (yet) available as scanned pdf in the internet. One has to buy the book, expensive, but it is worth the money! Best regards, Michael

Request: Huhu! Den hier hatte ich schon unter Pseudoophonus rufipes abgehakt, jetzt kommen mir aber Zweifel, obs nicht doch ein griseus ist. Länge hatte ich allerdings mit 12 oder 13mm notiert (aus der Erinnerung). Gefunden im eher waldarmen Waldlabor Köln am 20.06.2013, auf 57m üNN. Habt ihr eine andere Meinung dazu? Besten Dank und liebe Grüße!

Comment: Hallo Rüsselkäferin, für mich passt Harpalus rufipes (wie er jetzt heißt) schon, die Halsschildhinterecken sind aus meiner Sicht rechtwinklig und nicht gerundet. lg gernot
