I found a tiny patch of web on one of my aubergine leaves today, but I thought RSM was not a common problem outdoors. Could it be something else? What action should I take*.

False alarm, I have just discovered the culprit; a little green caterpillar thing about 3mm long, these appeared on my chillies last year, I have no idea what they are, oddly I mentioned them here just yesterday.
