Insect traits you could nab could include all-around vision, some kind of fly-like reflexes (Improved Initiative?), associated natural attacks (including poison?), and hivemind abilities (No member of the hivemind is surprised unless all are, ditto for flanking).
Also: Loved your work on the Marine and the Risen.
