nice paintings Jorge!

ehh, I mean pictures

---

Nice try - Ectophasia sp. Well, I say that based on the fact that vein-M is not petiolate and the wing pattern is diffuse but I don't recognise this species.

---

can I ask why?

It could be crassipennis? or is this another one?

---

ouch... don?t tell anyone! shiuu.

---

I only have crassipennis and oblonga in the Central European key and crassipennis is the most likely ... but I am not sure if you have more species down there

---

This is definitly not Ectophasia oblonga. A third species of Ectophasia exists: Ectophasia leucoptera. And this is it, most likely, because of the colour of the wings.

thanks. let?s go wait for Theo confirmation..

---

Without a doubt a male of leucoptera.
(black vitta on abdomen strongly broadened, milky colour of wings...)
Jorge, how do you get 2:1 maginification ?
100mm macro and intermediate rings ?
Nice work.

no. I use kenko extension tubes and Sigma 105 mm EX. I can get 4:1 with 50 mm inverted lens but it turns very hard to take photos. Very small depth of field and we almost see nothing. So we must illuminate the object.

---

extension tubes, that''s the word I was looking for.

Thanks
