Hi,

I just noticed one of my chilli pepper plants was starting to die and on closer inspection found it covered in these little suckers. There appears to be 3 different types. Can anyone help identifying what they are? I want to make sure I kill them good!

Background: The plants are located in Brisbane Australia and the insects seem to prefer the Chilli's because they're not on Basil and Tomato plants located immediately beside them (not yet at least).
