As food in the desert is scarce, the plates on Diloweed's back absorb solar energy. It curls itself up into a ball and lets the wind carry it if it is tired.
The Diloweed, Phlask and Vectol lines were the last evolutionary lines to be confirmed.
The Diloweed line was the last evolutionary line to not have any sprites.
The final design for Diloweed was made by a different artist than the design for Pangolash. Both artists also created designs for the other Pokémon in this evolutionary line, which lost to the other artist's design.
Diloweed was originally not intended to evolve.
It has been suggested that Diloweed be found within Rock Smash boulders, or as a unique smashable overworld object.
The Diloweed line was the only Pokémon in Pokémon Sage that made it past a concept stage that was considered to be culled.
