Banderas Bay Butterfies / Texan Crescent (Anthanassa texana)

by Moralea Milne

Texan Crescents are small (approx. 1.5 in or 4 cm) butterflies found throughout Mexico, in many different types of ecosystems. They lay their eggs on low lying members of the Acanthus family which generally have colourful, tubular flowers such a wild petunias, flamingo plants, black-eyed Susan vine, shrimp plants and others. These delightful small butterflies are quite common, but information on them is not. A paucity of information on most butterflies found in Mexico is more the rule than the exception. Still, I am grateful to find out any facts, particularly their identification and their larval food plants


  1. HI Moralea,

    I mentioned earlier on how few butterflies I have seen around my home in San Francisco, CA, this past year. However, I now report that during my recent two week vacation in Puerto Vallarta, I do not remember seeing one butterfly.

    But what I did read and see, was the Internet report and picture of a couple in Ohio spotting a black thunderbird in a field, and when it took off and opened its some 45 foot wingspan, larger than a small airplane, it wobbled as it attempted to gain speed and altitude for flight.

    That actual picture of a black thunderbird was taken in a museum hung up in a vertical position with its tail down and wings spread, and with a man standing alongside the bird. It was over twice the man’s height.

    I mentioned this occurrence that happened in Ohio during the first week of my vacation this year in PV, because I have not seen one of these huge birds gliding high in the sky over Puerto Vallarta for the past 20 some years.

    Whether this is due to the higher activity at the newer PV airport, climate or weather change, is a mystery . In the early years of my travels to Mexico, I was told by the Mexican recreation director at the Canto del Sol Timeshare Resort, that these large birds slept perched on trees in the Jungle at night, and during the day, just glided high in the sky without landing.

    In Canada there are many stories of the Thunderbirds, and are shown on the carved totem wood log tree poles . I have two large and four small totem poles , a tall one from Canada, and the other tall one from Indonesia. So the thunderbird must have been wide spread at one time.

    Do you have any interesting information regarding this, for information is scarce as sometime butterflies seem to be. My dictionary says that the thunderbird is a mythology of certain N. American Indians , an enormous bird, that produces thunder, lightning, and rain.

    Why… this could be the cause of all the thunder , lightning and rain produced in the jungle behind Puerto Vallarta.

    PS: I also have two fur seal skinned face masks from either Alaska or Canada. I acquired them both from my local flea market, from persons that were quite old, and looked like Indians from the far north. One actually apologized to me that the sealskin face mask was very old and somewhat warn. Amazing , I purchased them both for only $5.00 each, whereas I expected them to be worth hundreds of dollars each.
