Final insectoid design

Through my initial sketches and research, i found that the praying mantis was the most interesting of the insects that i was looking at and i decided that i would adapt my main design around that insect, combining assets from the other insects that i researched such as the rhinoceros beetles horns and dragon fly wing pattern.
I have called my insectoid, the Mantis Guardian. Sacrificing its claws, it equips dual scythe rifles which are fed ammunition from the poison sac on the guardians back which would usually be feeding into its claws, instead is now processing the poison into bio-bullets inside the rifles inner mechanism. When the need for melee combat arises the guardian will charge in at great speed provided by its wings and headbutt its opponent with its helm, if the initial blow wasn't fatal enough the disoriented target would then have to fend off the guardians swift attacks from the scythe rifles blades.
