|Ceutorhynchus sulcicollis |
This species may be present where brassicaceous herbs can be found.
Probably one generation per year. The species has been collected in North America from May to August.
Acording to the description given by Blatchley & Leng (1916), adults are oblong-oval, steel blue, and have few scales above. There is a faint scutellar spot (grouping of scales at the base of the thorax and elytra) present. The scales are much denser below. The funicle (antennal segments between the scape and the clubbed) is seven segmented. The beak is curved, slender and slightly longer than the thorax. The hind fermora as well as the tarsal claws are both toothed. Length 2.7 – 3.2 mm (Blatchley & Leng 1916).
The larva most likely inhabit the stems, seeds or seed stems of brassicaceous herbs, like other members of their tribe (Blatchley & Leng 1916). The adults feed on several members of the Brassicaceae (Colonnelli 2004).
There is no evidence this species is in need of conservation.
This species has been found on several members of the Brassicaceae as well as Reseda luteola L. (Colonnelli 2004).
The species has a Palaearctic distribution (Colonnelli 2004) but is also present across much of North America (Blatchley & Leng 1916).
Recently reclassified from Ceutorhynchus cyanipennis.
