Insects of Lanjak-Entimau

The following summary is an abstract from the "Development of Lanjak-Entimau Wildlife Sanctuary As a Totally Protected Area, (Phase II). Report on the Insects of Lanjak-Entimau Wildlife Sanctuary." By Chey Vun Khen, Sept. 1988.

The insect fauna was found to be exceedingly rich. A grand total of 6176 specimens, from 8 orders and 58 families, with 1053 sorted species, was sampled.

The montane forest at Bukit Lanjak summit, despite its small sample, gives a high proportion of unique moths not found at lower altitudes. Alluvial forest gives the lowest moth diversity while the secondary forest site, consisting of a mosaic of previous swidden plots to regenerated forest yields many big, attractive moths.

The beautiful Rajah Brooke's Birdwing (Troides brookiana brookiana Wallace), getting scarce in other parts of Borneo, is most abundant in the alluvial forest of Nanga Joh. Several endemic butterfly species are found in the lowland forest of Ulu Engkari, underlining the conservation importance of the site.

Dragonflies and damselflies found along the rivers of undisturbed forest of Lanjak-Entimau Wildlife Sanctuary show distinct species composition, with many species confined to the undisturbed habitats.

Bees were found to be unexpectedly low in abundance in the deep forest understorey.

Termites were found to be rather diverse. 40 species out of 100 odd known in Borneo, but pest termites, common in plantation monocultures, are rare in Lanjak-Entimau Wildlife Sanctuary.
