AbstractRecent observations on Harpalus griseus: is there a trend (Coleoptera: Carabidae)?
Harpalus (Pseudoophonus) griseus is reported in literature to be a rare ground beetle in the
Netherlands. Recently, many specimens of this species were observed or collected by means of
pitfall traps, window traps and light traps. Besides a number of observations from heathland
and drift sand areas
in the Veluwe region, H. griseus was collected in several agricultural and anthropogenic
habitats around Wageningen. Based on our recent observations the species seems to be more
eurytopic than previously thought. The total number of records shows a remarkable increase
during the last decade, while the distribution area seems to decrease. It is clear that, due to
different sampling intensities and collecting methods, it is impossible to successfully interpret
any trend. This is not only true for H. griseus: time trend analysis for all carabids and species of
many other invertebrate taxa, will be problematic in the absence of a valid procedure to correct
for sampling intensity.
