Pachygonidia odile, (wingspan (approximately): males: 65mm ; females: 69mm), flies in
Ecuador: Pichincha. The specimen depicted above is the only one known in European collections as of February 28, 2005.

The species is named for Jean Haxaire's wife, Odile, and Jean Haxaire and Ulf Eitschberger decided to go with her actual name rather than to go with the convention of "odilae". I asked him about the pronunciation of Odile and he wrote back "as in daffodil". Thus, in the suggested pronunciation, I am going with the actual pronunciation of the honoree's name rather than any latinizing of it. My own personal preference is that other namers/describers do as Jean and Ulf have done when it comes to honorific names for species or subspecies. I do not like the convention of the "i" or "ii" endings for male honorees and "ae" for female honorees.


There are probably several flights throughout the year.

Horst Kach sent me this image of Pachygonidia subhamata (bottom right) from Los Bancos, Pichincha Province, Ecuador, along with three specimens of the very rare Pachygonidia odile (one female top left), all captured between November and April, 2003 and 2004.


Larvae probably pupate in thin-walled cocoons under leaf litter.


Females call in the males with a pheromone released from a gland at the tip of the abdomen.


Mature larvae probably descend host to pupate amongst leaf litter.
