[Note Guidelines] Photographer's Note
From the backyard:

I am pleased to present you the 7 mm long progeny of the wasp I was observing laying eggs, the very wasp I had shown you before on TN: the larvae of the Black Rose Sawfly (Hymenoptera; Symphyta; Argidae; Arge pagana (Panzer); Blauschwarze Bürstenhorn-Blattwespe; Hilotome noir et jaune). The larvae eat the leaves of Wild rose, sticking together as a family. They even synchronize their behaviour! When disturbed, they lift their abdomen into the air, all at the same time (see here). How does such behaviour profit the animals? My guess is that synchronized movements might suggest a huge "monster" to a predator.

These larvae resemble caterpillars but there is only the first abdominal segment, not the two first like in caterpillars that lack abdominal legs.

Superb capture Dietrich!
I like the lighting shining through these sawfly larvae. Their uniform positions indicate their tendency to synchronised movement, which I, like you, believe to be anti-predator behaviour.
Excellent sharpness, composition and colours too.
Thank you and best regards,

really excellent photograph with great colors. wonderful colors and wonderful species. good clarity and sharpness. tfs.

Lovely lighting for these tiny caterpillars devouring the leaf in unison, fine capture. tfs.

A captivating image with impressive observations. regards yiannis

What's really funny in this composition is the legs of each larva curl around each edge... giving an apparition of a much bigger bug! Wonderful light!! TFS!!!

Amazing piece of work Dietrich, the colours and details you have captured are outstanding. Thank you for this great work.

Lieber Dieter,
spannend dokumentierte Entwicklungsgeschichte, vorzüglich ins Bild gesetzt.
Besonders interessant finde ich die Beobachtung der synchronisierten Abwehrbewegungen, die ein einzelnes abschreckend großes Tier vorzutäuschen scheinen.
Mit Dank und herzlichen Grüssen,
