The integration of different approaches in biology and ecology is rarely done. Most studies deal separately with faunistics, biology, distribution modelling based on abiotic data only, and ecology, and the use of molecular techniques and data is almost never linked to the above mentioned approaches.
The objective of this presentation is to show that it is possible to bring together these datasets to try to produce a more complete and realistic picture of a biological field situation in Lepidoptera, whether it is based on a conservation objective or for the control of invasive alien species.
The main profile will be the species Baronia brevicornis, a butterfly strictly endemic to Mexico and which is the oldest (Cretaceous) lineage of Lepidoptera in the world. The objective is to clarify the IUCN status for this mythical species.
A secondary study will focus on a species specializing in Brassicaceae -Plutella xylostela- which poses serious problems in agronomy.
It will be shown the limits of data integration when the origin of an economically problematic species with a worldwide distribution is not known.
