The only organisms that have backbones are the vertebrates, which include fishes, amphibians, reptiles, birds, and mammals. The invertebrates are all the other animals that do not have backbones. However, there are lots of other organisms that don't have backbones, such as plants, fungi, algae, protozoans, and bacteria. So really, the better question is, "which organisms do have backbones?", and then once that question is answered, your question can be answered as "everything else".
Nope, since a mosquito is an invertebrate insect it does not have a backbone. You certainly won't find a backbone on a mosquito!
No because they are an insect and insects don't have backbones.
The bogong moth is, well, a moth. A moth is an insect, and insects do not have backbones. And the term "vertebrate" refers to an animal with a backbone. No moth is a vertebrate, nor is any other insect.

No, but they have exoskeletons.
None. They are invertebrates, which mean they do not have backbones, or bones of any type.
Answer: All of them.There are no insects with backbones, in fact there are no Arthropods with backbones. Their support system is their exoskeleton, which is the tough outer layer made of chitin. Some insect's exoskeletons are harder than others, but all insects are boneless.
