here are some more Biolleyana from the other side of Costa Rica (Pacific). these look like B. pictifrons and B. fenestra adults, and an unknown juvenile with the wax tail.
the Caribbean equivalents in this post below (though I think that species can be found in both regions)
[ID: Traditional artwork featuring a variety of characters from different media. The first two star Frank Frankly from Welcome Home, the first with him standing, arms crossed as he surveys the audience and realistic bugs little the background, along with random shapes and colors. The other has him sitting in front of a white background, seemingly discussing insects. The next drawing features Blossom from the Powerpuff Girls, exclaiming something as she points vaguely to her right. Finally, the last drawing is of Danny Fenton from Danny Phantom, in ghost form as energy emanates from his hands, looking serious with a swirly green background behind him. End ID]
