I don't know what article in particular you got that from but the first sentence on the wikipedia page for https://en.m.wikipedia.org/wiki/Hemolymph literally says "Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod body remaining in direct contact with the animal's tissues."

It literally says its similar to blood in vertebrates in the first sentence... that seems proof enough.
