<p><strong>Background. </strong>Plants in the neotropical region provide different ecological services and sustain entomofauna biodiversity. The butterfly, <em>Morpho helenor montezuma</em>, has high economic value worldwide, derived from recreational activities. To enhance its sustainable use, it is important to know the spatial relationship of this species with its host-plants. <strong>Objective.</strong> To estimate the potential geographical areas in Mexico of three host-plants: <em>Bauhinia divaricata</em>, <em>Andira inermis </em>and <em>Pterocarpus rohrii</em> and their spatial relationship with <em>M</em>. <em>helenor montezuma</em>. <strong>Methodology.</strong> Distribution models of the species were generated using MaxEnt, employing predictive variables based on temperature and precipitation, and records of presence data. Subsequently, a joint analysis of layers was performed to determine the overlap in the distributions. <strong>Results. </strong>The models were appropriate as the area under the curve ranged from 0.86 to 0.96. The broadest potential host-plant distribution was for <em>B</em>.<em> divaricata </em>(30%), followed by <em>A</em>.<em> inermis</em> (21%) and <em>P</em>. <em>rohrii</em> with 7% of the country. In general, the joint distribution of the plant species is neotropical, and can be found in Veracruz, Tabasco, Chiapas and Oaxaca. <strong>Implications.</strong> The knowledge of the distributions of the plants allows their prioritization for conservation management and entomotourism. <strong>Conclusion.</strong> The joint distribution of <em>B</em>. <em>divaricata</em> against that of <em>M</em>. <em>helenor montezuma</em> had the greatest overlap (61%), with regard to the type of climate the highest concordance was found with <em>P</em>. <em>rohrii</em>. Pertinence to entomotourism and conservation planning is discussed.</p>
