The relative abundance of Coleoptera was the highest in the habitats with dense plant cover (III and IV), the number of carabids
and rove beetles per trap was also the highest in these habitats.
For example, scarabaeids were present at 63% and 64% volumes for the respective 28 May and 23 July samples; followed by the overlapping curculionids at 25% and 42% volumes for 23 and 31 July, respectively; and then carabids
at 40% and 65% volumes for 31 July and 9 August, respectively (Table 1).
There have been some studies of carabids
from the Amanos Mountains (Korell 1988, 2001), but there are no published records of Perileptus from this region.
Other species present on the island that are in a poor conservation status, include the carabids
(Asaphidion delatorrei, Dicrodontus alluaudi, Pseudomyas dorasensis and Paradromius tamaranus).
and staphylinids are a major component of the predatory ground fauna, while the scarab beetles tend to feed on foliage, detritus, and dung.
Other species of herbivores that spend a large proportion of their life cycles in cryptic locations are not susceptible to significant predation by carabids
, staphylinids, and spiders but are susceptible to specialist natural enemies (Ramert & Ekbom 1996).
Essentially serving as woodland refugia, these sites are dominated numerically by tenebrionids, although the stabilized soils and accumulated humus and leaf litter contribute to habitats capable of supporting a great taxonomic array of carabids
and scarabaeoids at all life stages.
That clue led to tests in which the researchers discovered that these carabids
move considerably farther and faster than anyone had suspected.
Both the adult and larvae ground beetles - or carabids
- are useful predators.
For example granivorous/herbivorous carabids
have evolved a large retinacular ridge on their mandible, which is used to grind seeds (Acorn & Ball 1991).
Recolonization and distribution of spiders and carabids
in cereal fields after spring sowing.
Pitfall traps are efficient and cost effective for passively capturing insects for many ecological studies, and have been used extensively for population studies of numerous ground-dwelling arthropods, including arachnids, formicids, Coleoptera and most notably carabids
(Southwood 1978; Post et al.
