Hi all
Came across a different bug today. It was on a bare lower twig on a Jacaranda tree. I think there were actually 2 of these 'things' tightly together.
I pulled them off the twig - the white 'cocoons'? were about an inch long. Inside was an orange/red gunge, but then I saw little orange/red critters! I think the gunge was actually a load of eggs or immature critters.
I've put the pics in iNaturalist but haven't had any responses yet.
Whatever they were they got comprehensively squashed!
