Synonyms and other taxonomic changes
Neurocolpus nubilus (Say, 1832)

Capsus nubilus Say, 1832
Capsus hirsutulus Walker, 1873
Neurocolpus rubidus Knight, 1934
Knight: male 6.5, female 7.0
Kelton: 7.0 - 7.7
Henry: 6.42-7.33 mm (male), 6.58-7.25 (female) (1)
N. nubilus can be distinguished from all other Neurocolpus species by:
1) A1/A2 = 0.48-0.60 (male), 0.52-0.62 (female);
2) A1 ≒ mesal length of pronotum;
3) Rostrum reaching metacoxae; and
4) Overall mottled pale to fuscous dorsum. (1)

"N. nubilus could be confused with N. jessiae, but the latter has a greenish-yellow tinge on pale areas, the areas posterior to the pronotal collar and between calli are pale, and on light forms only the apical 1/4 of the metafemora is dark brwon or black." (1)

"Antennal segment I not wider at apex; Antennal segment I not equal to more than two-thirds the length of segment II; rostrum not exceeding posterior margins of hind coxae” Source: Knight, 1934
Common in all the eastern states and southern Canada (Knight, 1924). Since then, it seems to progress westward.
Host plants:
Knight: “Buttonbush (Cephalanthus occidentalis); cottonwood (Populus deltoides), Kentucky coffee tree (Gymnocladus dioica); willow (Salix sp.).”
Blatchley: “Occurs on foliage and flowers of shrubs and herbs, especially in and along the margins of dense moist woodlands.”

Has been found on over 40 different plants, though some may be incidental.
