[Fish Sandwich]

One thing I came across in my (apparently now obligatory) reading of the Japanese Wikipedia page for the show that really fascinated me was that they wanted to come up with a way to differentiate Kabuto from the swarms of other beetle heroes already out there, and that the idea they landed on for that was to have his head be an entire beetle, rather than just the horns like your Kuugas and your Blades. It's fairly subtle on the final design, but looking at it with that concept in mind, it seems pretty clear that, for instance, the black bits on the side are representing legs.

I don't think it's a hard rule, but an entire insect for a face with another one on the body seems to be the basic Kabuto design pattern, and I love that despite emphasizing the "cool" factor so much, this show's Riders still have that same sort of whimsy to the way their motifs are incorporated that makes Rider and Sentai designs in general so endlessly fascinating. It won't be the first (or the last) time this gets said in the thread, but Kabuto really did utterly nail it when it came to aesthetics. Seeing them all in action rewatching the show is reminding me just how much I love basically all of these guys.
