The Fascinating Insect World of Trus Madi.

By Alan OwYong.

In 1986, Philip Chew found many rare plants and orchids in a regenerated forest at the heart of the Trus Madi range. Together with his brother Jimmy and friend Tam, they pooled their retirement funds and proceeds from sale of their homes to set up the Tras Madi Conservation Area. Their aim was to preserve the biodiversity of the 747 square meters of the conservation area. Their efforts paid off when it was designated as Class 1 forest reserve. In 2006 they were given an operation permit to set up a camp inside the area. The Trus Madi Entomology Camp better known as the Borneo Jungle Girl Camp was born.

The present day camp was a far cry from the first camp which was a single tent. You will be shown videos of how they dragged each cabin on logs from Apin Apin to the site.

Today the Entomology Camp is well known globally as the center for the study of insects and moths in Borneo. Against all odds they had created ” something out of nothing”. Unfortunately Philip passed away and Jimmy is left to carry on with his legacy today.

We ( Wilson Leung and his wife Theresa) were indeed privileged to be able to experience the magic of this world in June 2022 with the help of David Tseu, a Sabah based wildlife guide. Here are some of the more colorful moths and fascinating insects that we saw during our 4 days stay. Credit to iNaturalist for some of the identifications which are subject to confirmation from the experts and notes from Wikipedia.
