Yingabruxia brisleyi (Blake)

(Figs. 118–119, 171)

Reared specimens. ARIZONA: Maricopa Co., Tonto National Forest, east of Tortilla Flat, 6.iii.2017, em. by 3– 17.iv.2017, C.S. Eiseman, ex Lycium exsertum, # CSE 3359 (8 adults, MLBM).

Hosts. Amaranthaceae: Chenopodium album L. (Blake 1939); * Solanaceae: Lycium exsertum A.Gray. Santiago-Blay (2004) lists Amaranthaceae: Atriplex semibaccata R.Br. as a host for this species, apparently referring to adults.

Biology. The type series was reared from Chenopodium but no details were provided (Blake 1939). On Lycium, larvae formed small, full-depth, blotch or occasionally linear mines, which were largely clean as larvae deposited much of the frass on the leaf surface while establishing new mines (Figs. 118–119). They pupated in soil or, if no soil was available, in loose cocoons spun in crumpled pieces of toilet paper.

Notes. This is apparently the first Yingabruxia species to be reared from Lycium, although adults of both Y. batisia (Blatchley) and Y. sordida (LeConte) have been collected repeatedly on Lycium spp. (Clark et al. 2004).
