It's think it's very fitting. The dung beetle is the worldly embodiment of Sisyphus. Doomed to forever push a boulder uphill only for it to roll down again when he was near the top.
although probably unintentional, there's a bit of synchronism too, since the dung beetle (aka scarab) is the ancient Egyptian (Coptic) symbol of resurrection (among other things).
The way it's been described to me, the ancient Egyptians viewed dung beetles sort of like a phoenix (phoenices?) or an ouroborous, because they believed the beetles to have the power of self-creation (from the mistaken assumption that a dung beetle could survive entirely on dung it produced itself). So I wouldn't be so sure it's an unintentional reference.
