genitalia with aedeagus as in figures 707, 708. 
Host/Early Stages. Lupinus pratensis, L. vari- 
color, probably L. arboreus , L. latifoTius , and 
other species. Larva forming irregular linear 
mine on both upper and lower surface. 
Distribution. California. 
Reference. Spencer, 1981: 244. 
Frons slightly projecting above eye; gena 0.33 
height of eye L. huidobrensis (Blanchard) 
Synopsis. Frons orange yellow, upper orbit slight- 
ly darkened at least to upper ors; 3d antennal 
segment normally brownish yellow, in palest speci- 
mens only slightly infuscated; mesonotum black, 
appearing somewhat matt viewed from front; meso- 
pleuron variable but generally black on lower 0.75 
(fig. 709), in darkest specimens only narrow yel- 
low band along upper margin; legs with coxae yel- 
lowish black, femora basically yellow but variably 
darkened with black striations, sometimes appear- 
ing almost completely black but yellow always de- 
tectable below, tibiae and tarsi brownish to 
black; squama yellow, margin and fringe black; 
wing length 1.7-2.25 mm, discal cell relatively 
large (fig. 710), last section of M 3+4 only 2-2.5 
times length of penultimate; male genitalia with 
aedeagus as in figures 711, 712. 
Host/Early Stages. A highly polyphagous species, 
with confirmed records on 10 families - Apiaceae, 
Asteraceae, Chenopodiaceae , Cucurbitaceae , 
Fabaceae, Liliaceae, Linaceae, Solanaceae, Tro- 
paeolaceae, and Violaceae; crop plants attacked 
include A1 1 ium cepa , Apium graveolens , Beta vul- 
garis , Capsicum annuura, Cucumis melo , Lactuca 
sativa , Linum usitatissimum , Lycopersicon esculen- 
tum , Pisum sativum , Solanum tuberosum , Spinacia 
oleracea , and Vicia faba . Leaf mines also occur 
on many ornamentals; leaf mine (fig. 713) normally 
associated with midrib but can be obscured when 
many larvae feed together in same leaf; puparium 
yellowish or reddish brown, posterior spiracles 
each with ellipse of 6-9 bulbs (fig. 714).
