Mimbalot Falls is among the earliest sites for my odonatalogical adventures. I first visited the area in 2000. Then, the dirt road going to the waterfall was rough. It was very dusty when you visit during dry period while several small puddles line the road during wet season. The surrounding area was lined by several old secondary trees making the ground moist. (This is no longer the case today. Several infrastructures dotted the area.)
No houses and other infrastructures were present in the area except for an abandoned pool. This pool provided me with several interesting species of dragonfly. That was the first time I saw a white dragonfly – Zyxomma obtusum, now I knew this species is very abundant not only in Mimbalot Falls but across the Philippine archipelago.
Although Mimbalot Falls is not very high as compared to other well-known waterfalls in the city, it is the most accessible waterfall in the city dubbed as “city of waterfalls”. Mimbalot Falls is situated in Buru-un, Iligan City. It is a few minutes walk from the national highway and less than five minutes if riding a vehicle.
My first new species of damselfly came from Mimbalot Falls. I recorded several adult and secured a few voucher for my collection. Then, I did not realize that what I found is a new species until four years after when Drs. Jan van Tol and Vincent Kalkman came and visit Mindanao for the Philippine - Netherlands Biodiversity Research Program. Presently, the species is named Drepanosticta krios by Dr. Jan van Tol.
During my first few visits in Mimbalot Falls, Devadatta podolestoides basilanensis was so abundant even near the road (This species is a good determinant of habitat degradation). This is no longer the case today and finding one individual is not that easy as ten years ago. In this waterfall, I first noted the shift of species composition across time and across gradation of habitat loss. Now, I could no longer find some of the species I recorded in the area a decade ago.
