Illustrated from live specimen observed at Catalina State Park, Pima Co., Arizona. 28 Marche 1994. a) Elada Checkerspot, Texola elada.
FLOWERS: Orange-Red, tubular, flowers have four, recurved
petals. There are two long stamens with conspicuous yellow-tipped anthers.
Flowering through much of year but peaking April and May.
A very small orange and black butterfly, the Elada Checkerspot, is commonly encountered near this plant because the caterpillar stage feeds upon the leaves. The flowers are highly attractive to hummingbirds.
