Bugs on my Onc...and what looks like a bug egg... what are they and what do I do?!!!

[RosieC]

While watering my Onc Sweet Sugar this morning I spotted bugs. My first thought was greenfly but I don't think they actually look like greenfly. Can anyone tell me what they are
please click on the pics for a big version where you can see the bugs semi-clearly



There is also an egg like thing on a stalk which might help with ID of the culprit.



I have never had bugs on orchids so don't have anything specific to treat them. I do have a spray which I use for greenfly in the garden which also says it is good for other bugs... is it likely to be safe to use on my onc. The bugs are all over the flowers (although only in one spot at the momment) and I would hate to kill the flowers but if I have to I will.

Also my Mum just uses soapy water on greenfly... is that likely to work do you think?

Please help... this is the first time I've had any bugs of any sort on an orchid and I'm in a bit of a panic
