A Hierodula species makes sense. The various body part shapes and construction fit that species much better than any Creobroter species of which I could find pictures.
What is Hierodula solomonensis? I did a Google search and found virtually nothing on them. Does that species gave a common name? Is that red/orange color common for immature examples? What color do the adults have?
Maybe Mr. Siwanowicz altered the colors for artistic reasons....
