Ah, the humble Wurmple. Despite its prevalency through the Hoenn region, its true nature continues to illude scientists to this day. The issue? It seems that, despite their differences when fully evolved, it is impossible to distinguish between the larval forms of the Papilio venatus (Plate XII) and the Actias venenum (Plate XIII).

It has been suggested that perhaps this is an example of convergent evolution, but this hypothesis has been muddied by recent studies that show that even eggs from the same brood can experience different evolutionary paths! I for one am unsure of what to make of this discovery...

As a result, those who specifically desire one or the other are advised to instead search for their intermediary chrysalis forms, which are more easily distinguished -- that is, Silcoon (which evolve into Beautifly) are more pale in color than Cascoon (which evolve into Dustox). Still, it's common for young trainers to make bets with their friends over which evolution will occur.

In regards to what we can observe, both of these fine insects can adapt readily to various climates, but seem to particularly thrive in the forests of south-eastern Hoenn. Keep in mind: specimens from different regions may have minor variations compared to what is pictured here. For example, Dustox from the areas around Mt. Chimney may appear more blue-greenish in hue, while those from more southern regions tend to be more yellow-green.

As always, it is recommended for average citizens without proper training in handing Pokémon to maintain a safe distance from both of these species! Despite its eponymous beauty, Beautifly are known to be quite aggressive and territorial. Similarly, while Dustox are much more docile in nature, toxic dust is scattered through the air as they flap their wings. There are many different municipal approaches to prevent Dustox from congregating within city borders, but, in case of emergency, antidotes are available at any cornerstore.
