Longitarsus melanurus (Melsheimer) was first associated with Onosmodium Michx. by Popenoe (1877) in Kansas where the sole species is O. molle Michx. (Great Plains Flora Assn. 1986). Recent field observations over several years showed that adults of L. melanurus feed on leaves of O. molle in Wisconsin, where these beetles were collected at 43 of the 59 sites where O. molle was found growing naturally (Williams 1996)

LONGITARSUS MELANURUS (COLEOPTERA: CHRYSOMELIDAE) 
REPRODUCES ON ONOSMODIUM MOLLE (BORAGINACEAE) 
Andrew H. Williams1  
Longitarsus melanurus (Melsheimer) was first associated with Onosmo-
dium Michx. by Popenoe (1877) in Kansas where the sole species is O. molle 
Michx. (Great Plains Flora Assn. 1986).  Recent field observations over several 
years showed that adults of L. melanurus feed on leaves of O. molle in Wiscon-
sin, where these beetles were collected at 43 of the 59 sites where O. molle was 
found growing naturally (Williams 1996).
On several occasions, L. melanurus adults were found feeding on leaves of 
Cynoglossum officinale L. (Boraginaceae) at sites where O. molle also occurred (Wil-
liams 1996).  These beetles were neither observed at these sites on foliage of several 
native borages: Lithospermum incisum Lehm. (31 sites), L. canescens (Michx.) 
Lehm. (30 sites), L. carolinense (Walter) MacMillan (1 site) and Hackelia virginiana 
(L.) I. M. Johnston (15 sites) nor were they seen on the exotics Lappula squarrosa 
(Retz.) Dumort (2 sites) and Echium vulgare L. (1 site) (Williams 1996).  Furth 
(1994) reported L. melanurus using E. vulgare in Massachusetts and New York.
A simple experiment was done to test whether or not L. melanurus would 
reproduce on O. molle.  Tiny, wild, bare rooted plants were potted and tightly 
caged.  These were maintained free of other plants and without evidence of L. 
melanurus being present for more than a year.  On 11 June 1996, 37 adults 
collected on O. molle in the wild that same day were introduced.  Adults were 
removed between 27 and 29 June.  The caged plants did not again harbor adults 
until 7 August.  Between 7 August and 24 September 1996, 102 adults were 
removed from these plants.  This shows that L. melanurus can reproduce on 
O. molle, the sole native species on which adults have been reported to feed 
(Popenoe 1877, Furth 1994, Williams 1996).
Specimens of L. melanurus were donated to the Insect Research Collec-
tion of the Entomology Department, University of Wisconsin - Madison.  Plant 
nomenclature herein follows Gleason and Cronquist (1991).
