Spotted lanternfly photographs

I’ve posted a few pics of the invasive spotted lanternfly (Lycorma delicatula) on Instagram but thought I’d feature my full collection in a post. The insect is extremely photogenic but it’s also good to let people know what different stages look like so that everyone can kill them. I still need some early-instar pics as well as some showing spotted lanternflies being consumed by parasites and fungi.
