|9145H CHLOROPS RUFESCENS COQUILLETT
January 1, 1990
Designation given to rearings of Chlorops rufescens Coquillett, 1910: 45. It has been recorded only from PA, but I have taken it also in northeastern Ohio.
Nothing is known of its biology or larval feeding habits. The immature stages are undescribed.
Rearing records are:

LARVAL FEEDING HABITS:
Swept numerous adults of Chlorops rufescens from a small stand of Carex vulpinoidea at the marsh along rt. 43 south of Streetsboro (Len's study marsh). First time I have been able to determine the host plant of this species. According to Braun (1967), this sedge belongs to a different subgenus (Vignea) than the species used by C. certimus (Eucarex). In the subgenus Vignea, the spikes are all alike with staminate flowers basal or apical, there are 2 stigmas, and the achenes are lenticular. In contrast, in the subgenus Eucarex, the spikes are either pistillate or staminate, there are 3 stigmas 3, and the achenes are 3-angled.
Swept up a single adult of this species while sweeping wetland plants behind the KSU stadium. It is quite possible that the host plant, Carex vulpinoidea, was in the vicinity.
Swept up a gravid female in my weekly sweep sampling of Juncus tenuis near Walls School. Growing near the stand of the rush were a few plants of Carex vulpinoidea
, and I suspect that this species is the host plant..
