And changed to chosen of Jergal. Jergal looks like a cross between a praying mantis and an ant-man and Jergal plays an important role in getting souls to their proper afterlife. If Jergal has been trapped in tomb for years then there is a backlog of souls who are vulnerable to depredations of devils and demons.
Deities can assume multiple forms, and one of Jergal's forms is a praying mantis/ant-man, yes. That doesn't mean he always appears as a praying mantis-like being. He can also take the form of a "mortal man with a great white beard" or any "undead creature".
