Hallo zusammen,

diese farbenfrohe Spinne saß heute (04.04.21) in meiner Wohnung (D, BW, Staufen im Breisgau) an der Wand; Länge maximal 2-3 mm. Könnte das ein Weibchen von Araniella opisthographa sein?

Danke und Gruß, Siggi

Hi Siegfried,
the spider is still immature (note the typical reddish color).
In addition to this, the species is not determinable for another reason: opisthographa always has 5 pairs of lateral points on the abdomen, on your animal I see 4, even if the fifth pair can develop later.
With 4 pairs, according to the "point pairs theory", in Germany there are cucurbitina and proxima.
So ...

Greetings from southern Italy.

Hallo zusammen,

mit dem vorne zugespitzten Opisthosoma, der rötlichen Grundfarbe und den weißen Seitenbändern, könnte es doch auch eine juvenile Araniella displicata sein, oder liege ich da falsch?

Liebe Grüße
Jutta

Yes, even a young displicata, sure.  ;)

Hallo Jutta, Raffaele,

many thanks for your detailed explanations. We now have three types in the running, only mine is not included  ;D That's typical for me. In this case I am writing Araniella sp. That’s definitely the case.

No, Siggi, the species you indicate is also in the running, read my first answer well. It is also possible that the fifth pair, being right above the spinnerets and being made up of 2 very small points, is not visible in the photos.
So opisthografa is in the race, only it is in last place, a bit like Ferrari compared to Mercedes in F1 in the recent years (but if there was Schumi ...).  :(

A greeting.

Hi Raffaele,

nice comparison. There is now a young Schumi. But it still needs some time. Thank you for your comforting words  8)

Greetings Siggi
