Please read the following recomendations:

RECOMENDATION 1: We accept images up to 1280x1280 pixels. In order to attach pictures to your post please refer to the instructions given at Images & Attachments, that is through the link Upload attachment.

RECOMENDATION 2: As a general rule, when you upload pictures of a specimen it is a good practice to provide additional information on location, date, approx. size of the specimen, notes on behaviour, environment, etc.

RECOMENDATION 3: Open one post per species. If you have some photos of a specimen "A" and some photos of another specimen "B" (different from "A"), open a post with the photos of "A" and another post with the photos of "B". This makes the forum more ordered.


The following is an example.

The specimen pictured here is a Chrysidid photographed in Italy, Bologna, 06/2009. The magnification ratio was about 1:1, with the specimen of about 6-7mm. The images are crops of the original shots. Shooting data: Canon EOS 40D, Canon EF 100/2.8 Macro USM, Canon Macro Ring MR-14EX, 1/250" @ F/8.0, 200 ISO.


The shape of the end of the abdomen (= anal edge) is of diagnostic importance in Chrysidids and it is useful to identify the species. Unfortunately, it must be emphasized that macrofotographs of specimens in nature rarely show enough resolution to identify the species for sure.

In our case, the ensemble represented by colors, shape of the abdomen, beveling of the anal edge - together with the period of activity and the location - is enough to identify the species with a good confidence as Chrysis interjecta.

Caspita,
complimenti :shock:
gran bella foto, ma soprattutto il colore sembra un po' troppo sfalsato verde oliva chiaro, è originale o un effetto :? ?

Ciao

Grazie!
Non ho fatto nessuna modifica (intenzionale) al bilanciamento. Secondo me è un effetto del flash usato a potenza maggiore di quello che era necessario (di qui il colore chiaro), su un esemplare che evidentemente tendeva già di suo al verde...
Ciao ciao,
