About us

Who is working on the Delias of the World website ?

On this site, you will find a complete list of all Delias species and subspecies, together with photographs and thumbnail notes relating to as many species as possible.

The aim is to make this site a complete reference for this genus.

This website is the result of the voluntary work of many entomologists who are passionate about Delias butterflies. 

Olivier PEQUIN

Owner of this website, I am a private researcher and an amateur entomologist. I have been studying Delias for over 20 years now. I have traveled to meet them in Southeast Asia, Australia, Papua. 
I had the chance to describe new species (Delias maaikeae) and subspecies of Delias (Delias dice burki). You can consult my scientific publications on Research Gate

Chris Davenport did me the honor of naming Delias vietnamensis pequini from Cambodia after me.

Chris DAVENPORT

Chris is a Scottish entomologist who has built over the years one of the major Delias collections in the World. Chris has also described a lot of Delias species and subspecies over the years. The beautiful photographic plates on this site were produced by Chris' meticulous work.
