Very interesting antennae... I'm confident its some kind of orthoptera (grasshopper) and due to the underdeveloped wing stubs its almost certainly a nymph unless the adults lack complete wings.

It will be impossible to tell the exact species due to the lack of visible characters in the photograph and the fact that this is a species form the Philippines.

Kind of reminds me of a Eumastacid or Proscopiid species. The prior are referred to as "matchstick" grasshoppers and lack developed wings while maintaining an elongate shape like the one you've posted.
