It’s my second time to visit the island of Siargao although I was here not to collect beetles but just to travel with a friend. But then, when we were in Taktak Falls, in the municipality of Sta. Monica which is located at the northern part of the island, a small pachyrrhynchine curculionid showed itself.
I’m not sure what the specific name of this Metapocyrtus sp. but the male was at a particular plant, probably feeding as the leaves showed signs of being chewed on. Not much were seen, only about two of these were at the same plant.e
While viewing my Twitter feed, one tweet from @markzambrano caught my attention:
Metallic colored beetles eating tree sap in Lantawan Eco Park, Kitcharao, Agusan del Norte.
From the included link, I just saw this beautiful congregation of such beautiful flower beetles, Heterorrhina (Heterorrhina) macleayi Kirby 1818. These beetles are rather common in the country and are usually abundant during these months. In the forests of Bukidnon where I used to go, in a single swipe of the net, more than a handful of different species of flower beetles (subfamily Cetoniinae, family Scarabaeidae) can be netted.
My thanx to Mark Zambrano for giving me permission to post this one. Follow him in Twitter: @MarkZambrano and Instagram. Mark is a Jounalist/Sports Correspondent/Senior News Anchor for GMA News and Public Affairs.
Cebu island is one of the country’s least explored and studied when it comes to Pachyrrhynchini. Despite being mountainous, most of its forests have already been cut as early as during the Spanish colonial period. With the boom in sugar prices in the late 19th century, much of the north have then been denuded to give way to vast sugar estates.
The remaining forests in very small patches in Central Cebu and perhaps at the southern end may still harbor interesting Pachyrrhynchini like this unidentified Metapocyrtus sp. (probably subgenus Trachycyrtus) found at a pile of cut chrysanthemum flowers in the province’s Transcentral Highway.
Dalla Torre and Emden’s Coleopterorum Catalogus and Schultze’s papers only mention quite a few, perhaps less than three species of genus Metapocyrtus and none of Pachyrrynchus. I’ve seen in the holdings of the University of San Carlos biological museum some species including ones that I’ve collected for myself.
I was walking along a street in Zamboanga City and when I was about to enter the hotel premises which was near the airport, I saw this beautiful and large Chalcosoma atlas LINNAEUS 1758 frantically trying to get up as it fell and was lying on the ground. Helpless. I reached for it then transferred to this wooden post.
No, it wasn’t killed for my collection but left it there.
