@KimPullen @MichaelMulvaney Appreciate some advice. There is so much more in this photo than I realised when I took it. Besides the leafhopper and attendant ants there are three other insects: two just at the tail end of the leafhopper. I'd have ID'ed them as leafhoppers except that they seem to have antennae. Also, are the yellow dots eggs, mites or scale? Thanks Alison
