the other is Araneidae - and it is Argiope bruennichi . Very common right now! Beware at the web. Sometimes you can see Milichiidae flies stole the food of spider. ;)

Hey! First of all, take it easy. Isidro, crex didn't anything... Valter, you must wait just one day, not 3-4 days. :) And remember that rules ask for one species for each thread to avoid confusion. Very soon it will appear some dedicated
fora concerning non-diptera insects.
ok. Your last spider is very easy to ID. In Portugal THERE IS ONLY one spider that makes a web like that, and your specimen fits 100% to Cyrtophora citricola (Araneidae). It is very common in South of Portugal. In North I never saw a Cyrtophora citricola. The most Northern spider C. citricola was spotted in Coimbra. They usually are associated with cacti and makes web very near each other - that's why they are called social spiders. (they are not really social... but it is an approximation! There are *really* SOCIAL spiders in Africa, for example, on high of trees.)
Remember, this forum is very good. We must be respectful and take care of it, specially in a forum with this quality.
Keep sending your photos, but one species for thread. :) You can send for one thread the photos you desire IF it is the same specimen. The best would be to have dorsal view, frontal view, rear view, and sometimes ventral view. :)

I add: it's probably thatt the second was not Argiope bruennichii but Argiope trifasciata. A dorsal view can confirm it.

i never seen
A.trifasciata (from what i know is not present in romania) but for sure this is not.
A.bruennichi, i have seen thousen of individual and...
in romania also
A.lobata (much much more rare than
bruennichi), again completely different. so you have to see in your species what is in plus there :D

more common is A. bruennichi at the right moment. I think there is strong evidence to be A. bruennichi, and Isidro is right: we need a dorsal view to confirm! :)

No, Jorge, the rings in the legs indicates A. trifasciata (A. bruennichi have different-sized rings), but as I said to be sure at 100% is necessary a dorsal view...
In my zone (Aragon) is slighthly more common A. lobata than A. bruennichi and A. trifasciata do not exist. In the rest of the country A. trifasciata is common in the South.

hmm... just now I realized that the photo was taken in ALgarve!!! :|
A. trifasciata known, at least, for South:
http://www.aranha...d=43&sp=42
A. bruennichi is very common in the North.
The rings not always are reliable characters.. still we need dorsal view! then any doubts will vanished. :)

I was right. It's Argiope trifasciata.
Valter, you must wait just one day, not 3-4 days

No doubts now... it is really an Argiope trifasciata. I was wrong.
The last one is 100% A. lobata. :)
yes.-- sometimes, it is enough one day. It depends though. :P
hymenoptera forum will take a while to appear. We must wait a little more.

valter.. it appear one empty thread today that Isidro took... Now, just tomorrow I think.
This system appeared because this a forum about diptera, and it was expected to have very few posts about non-diptera... but there were lots of them! So to avoid an avalanche of non-diptera threads it was created this system. I agree with this system.
One day it will be launch a forum in aranhas.info (just for Portuguese spiders like yours, though)
