Anelaphus brevidens (Schaeffer) . New larval

host records.

JV discovered this species in girdled living stems of Ericameria linearifolia (DC.) Urbatsch and Wussow (Asteraceae) from CA: Riverside Co., Pinyon Flat. The larva girdles the stem in which it fed and pupates below the girdle plugged with a conspicuous fibrous plug ( Fig. 1E ). The girdles were typically very close (5 cm) to the ground and the pupal cell sometimes extended into the roots. The habits are similar to Anelaphus inflaticollis Chemsak as described by Hovore and Giesbert (1976) and to the aforementioned Aneflomorpha species. Both teneral adults and prepupae were encountered in pupal cells in March.JValso found A. brevidens in a different, larger Ericameria at CA: San Diego Co., Kitchen Creek. Presumably because of the larger size of this plant, pupal cells were high above the ground within the thick stems. Anelaphus brevidens appears to utilize a variety of host plants because it was also found in girdled living C. eriophylla ( Fig. 1F ) from AZ: Pima Co., Tuscon and in a girdled terminal twig of M. dysocarpa from Pima Co., Madera Co.
