SeasonalityProbably one generation per year. Ceutorhynchus neglectus is common from June to August.
IdentificationAdults are small and round bodied (1-2 mm in length) with red-brown legs and dark bodies covered in white scales (Blatchley and Leng 1916). The proboscis is long and curved with small bent antennae at the proximal end. When disturbed, it displays the interesting behavior of folding its legs and proboscis against its body to make it look like a small dark pebble. Similar in appearance to its co-generic C. obstrictus it can be differentiated by its smaller size and dark body color.
