Explanation of Names
Calligrapha ancoralis Stål, 1860
ancoralis refers to the typical pattern on elytra.
In the typical pattern, the humeral moon-shaped macula is narrowly seperated from both the enclosed dark spot, and the subsutural band (on 2nd. interval).
The rear end of dark 3rd. interval is bending outwards, turning forward and may almost reach the humeral "moon", forming an anchor-like figure. This pattern can be broken into spots, however.
A dark spot at about the middle of elytral side margin always present, as in the C.scalaris-group. In the latter, black on 3rd. interval is not notably extending outwards.
s. AZ / Mexico, S to Veracruz and southern tip of Baja California. One old TX record to be considered doubtful (1)
Unknown. Several Mex. collections made on Tillandsia sp. (Bromeliaceae), but this is very unlikely a host, rather a good hideaway for summer diapause.
Not listed in Riley et al. (2003)(2)
, nor in Clark et al. (2004)(3)
Historical US records first reported by Gómez-Zurita (2015)(1)

one specimen: Nogales, Ariz. ix.25.1959, D.E. Noel, Calligrapha sp. det ’60 D.M. Weisman;
one specimen: U.S.A. Texas, Lee Co., Fedor, F. Monrós Collection 1959, Calligrapha wickhami Bowditch, F. Monrós det. 1954, Calligrapha ancoralis Stål J. Gómez-Zurita det. 2011
Note, the Lee Co., Texas record "is an extremely doubtful record." (1)
In addition, Gene Hall, University of Arizona Insect Collection Manager, reports (facebook, 2016) the following information from the UAIC:
"We have an old specimen of this species in the UAIC labeled "Ariz." from the CW Leng Collection, but unfortunately with no collecting date."
This minimally labeled spmn in the UAIC may be the source for Calligrapha ancoralis
being included in "The Leng Catalog"(4) here
