Carpet and Moss
The bright green of this moth larva caught my eye as I walked past. Investigation shows that it's the larva of the Common Marbled Carpet - a handsome moth that I've shown before.
Detail of the head end shows that the front legs are all condensed into one group, and that it has five ocelli or sub-eyes. These are the ripening capsules of the moss Bryum capillare:
What a shot! Given that I guess the whole thing is only an inch or so long at best. How far away/what lens? Tripod or are you just very, very good at holding still? Impressed!
Lens is the Canon 60 mm dedicated macro lens, effective 96mm, due to small sensor multiplication factor. I'd say I was about maybe 3" away.
>Tripod or are you just very, very good at holding still?
Hand-held, shooting at exposure priority of 1/160th to avoid handshake. This usually results in wide open aperture in our light, even at ISO 400, so DOF is around 1mm.
>Do all catties have ocelli?
I've seen various Pug moth larvae with 5 dark ones, and many Sawfly larvae have a single. Many don't have obvious ones, but they might just be the same colour as the rest of the head/eye, so not as obvious.
