Actually there are some insects that don't need hemolymph to live.

The Weta is probably the biggest example. Since it actually dies during the winter months and the comes back to life when it warms up.....except its actually no longer functionally alive anymore and the hemolymph is no longer required for it to function as

In other words, its basically undead.

So yeah, hemolymph isn't really required for some insects. Even if they have it, some of them don't really need it anymore.
