Rio Grande Valley Butterflies & Host Plants

This is meant to be an informative list of the butterflies documented in the Lower Rio Grande Valley and their known host plants. The area covered includes Cameron, Hidalgo, Starr, and Willacy counties. The butterfly species list comes from the National Butterfly Center’s Butterfly Checklist for the Rio Grande Valley. The known host plants are compiled from multiple sources, including the Butterflies and Moths of North America, Kaufman Field Guide to Butterflies of North America, and the Caterpillar Food Plants for the Lower Rio Grande Valley of Texas. When compiling the list, we relied heavily on iNaturalist for plant genera names, common names, and updating scientific names.

To use this resource, we recommend using the Find Command (Ctrl + F) to look up either the butterfly species common name you are looking for, or to see how many times a particular plant family, genus, or species is listed. If you look up Bordered Patch, for instance, you will find that there are 10 plant species listed as known host plants along with species of ragweeds (genus Ambrosia). When looking up the plant genus Abutilon you will find it is listed 7 times, and if you search for Wild Crapemyrtle (Malpighia glabra) you will find it is listed 6 times – that means that there are 7 butterfly species known to host on the former and 6 butterfly species known to host on the latter that have been documented in the Rio Grande Valley.

Other notes regarding the list:

* Butterfly names are in bold

* When a specific plant species is listed, it will include the common name followed by a scientific name in parenthesis; for example, Common Sunflower (Helianthus annuus).

* When only a genus is listed, the common name for the genus will be in all lowercase and followed by the scientific genus plus a “sp.” to abbreviate “species”; for example, oaks (Quercus sp.).

* Sometimes only the family of plants is listed – Mallow Family (sp.) – or none of the resources included any known host plants – those species we have denoted with “(sp.)”.

* Not all of the plant species included are listed as native to the region, so if you are planning to use this list to help design a butterfly garden please keep that in mind.

Lastly, if you are aware of other resources that we should add to our database, or have noticed any errors, please contact us at center4urbanecology@gmail.com.
