Phylogenetic Sequence # 190275
Forewing length: ♂ 10-13 mm, ♀ 10-15 mm.(1)
Adult: forewing ground color white but largely obscured by extensive dark transverse streaks; PM line thick, black, sinuous, interrupted by yellowish-orange blob near costa; AM and median lines blackish, diffuse, almost straight; band of dark gray shading immediately beyond PM line, followed by whitish transverse band representing a subterminal line; terminal line a series of black dashes; hindwing light yellowish-brown with conspicuous dark median line
* in south Texas Rindgea cyda can only be distinguished from the nearly identical R. s-signata by genitalia.(1)
Louisiana to southern California.
Recorded as vagrants in Oklahoma, Arkansas, Missouri and Kansas.(1)

(its presence on a list from New York presumably represents an accidental record)
Adults fly year round in the warmer areas.(1)
Adults fly from March to September in California.
Larvae feed on mesquite (Prosopis spp.) and beardtongue (Penstemon spp.).
The S-signata group consists of three very similar species. Please see notes on the range which is often helpful in determining the species.

6/5/2022 by Ann Hendrickson:
I have just discovered an error in the naming of the Male genitalia in the Ferguson fascicle on Page 340. Since I have made all of my identifications from the Male genitalia, I have missed this for YEARS!
I made this discovery when I recently reared Rindgea s-signata for the FIRST TIME. The mother dissects as the Ferguson R. s-signata while 5 males from the brood dissect as the Ferguson named Rindgea cyda photographs b & d! That would indicate that the female dissections are the ones that are correctly named.
The caterpillar posted on BOLD as TXLEP669-19, BIN, BOLD:AAF0914 was beaten from a Mesquite tree and matches Rindgea cyda, however, it is not Barcode compliant as is the comparison specimen. All of my barcode compliant specimens match. I am hoping that when I submit three specimens that dissect as R.s-signata, they will not match the others!
