Bug Eevee Evolution

I've always thought that bug type would be the most farfetched evolution for Eevee. My cousin told me once that they would probably make a bug type before they made a flying type, that was before black and white where there was a pure flying type though.
And like with the poison type Eeveelution I did, I tried to think of why an Eevee would need to turn into this.
My thinking was that Eevee living in rainforest caves had to do bug-like things to survive and over time took on this form.

It's looks are based on the Goliath beetle and Its name comes from the word kairomone.
