I literally found more pages confirming the comparison...

Blood: "Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen."

I can see the difference but its still being compared... also, why in the world would I contact a professional over an online debate, seems overly excessive...
