feeding upon the trumpel vine. Undoubtedly a much larger number 



of plants are also attacked.

Control. — Ordinarily the attack of this moth is not serious enough 

 to warrant control measures. However, in case remedies are thought 

 necessary, the application of arsenical dusts and sprays will prove 

 effective.

Egeria ewitiosa Say (Family iEgeriidae) 2 " 



[Sanninoidea ewitiosa (Say)] 



(Fig. 429) 



Description. — The adults are known as clear-winged moths because 

 of the lack of color-scales on some parts of the transparent membrane 

 between the veins of the wings. The wings are rather long and slender, 

 as are also the bodies, which cause them to be frequently mistaken for 

 large wasps. The females are iridescent steel-blue with purple or green- 

 ish reflections. There is a broad orange-colored band across the middle 

 of the abdomen. The fore wings are entirely covered with scales and 

 are opaque, while the hind wings are perfectly transparent excepting 

 the veins. The body is about f inch long and the wing expanse averages 

 H inches. The males are considerably smaller, of the same steel-blue 

 color, but lack the orange-colored band across the abdomen and instead 

 have bright yellow markings on the head, thorax and legs, two slender 

 bands on the abdomen, two light-colored and a black tuft at the end 

 of the abdomen. The wings are transparent, excepting a small blue 

 patch across the middle of the front pair. The eggs are oval or slightly 

 flattened, dull yellow with finely sculptured surface and ^ inch long. 

 The full-grown larvae or caterpillars are pale yellowish with brown 

 head and black mouth parts. There are three pairs of true legs and 

 five pairs of prolegs. The average length is from 1 to H inches. The 

 cocoons are made of frass, gum and silk and are very stiff pod-like 

 structures. In these the reddish-brown pupae are usually to be found 

 near the entrance of the old burrows, near the surface of the soil or

 dropped as synonyms of 38geria. The family name. SSgeriidm, also replaces Seaiida;.
