I found these dark brown eggs in several groups, on both sides of leaves of Citrus, in May 2012.
One group was on a stone wall.
They are ~ 0.8mm long. They have a translucent membranous flap at the end.

I know they are not:
- citrus leaf miner (Phyllocnistis citrella) because that moth lays its eggs singly,
- citrus shield bug (Rhynchocoris humeralis) because they are the wrong shape

I suppose I am not 100% sure they are eggs; they could be communal pupae, perhaps.

Any clues appreciated!
Mike

Hi Mike... I have been trying to determine if it might be citrus blackflies....the "cases" look to be in a sort of spiral formation and your pic is a wonderful extreme closeup....I am having a hard time finding one that clear to match it against.

themoonhowl,

Thanks for your thoughts.
Sorry for my belated reply. I thought the system would email me whenever there was an update to one of my postings, but apparently not.

That link is broken now, but I have done some more Googling and I see what you mean.
But I think the eggs are too different for it to be that species (Aleurocanthus woglumi ). However, I note some other species of Aleurocanthus lay their eggs more like mine, so maybe... However, I have found no exact match:(
I also have a feeling it may be within the Hemiptera (where the eggs are variable but often have a 'cap' somewhat like mine), but again I can't find an exact match.

Hi Mike....

that is the problem I have run into....no clearly definitive image...I see some things, but on closer inspection there is no clear match. We may have to wait til May again and see if they return.
