NAME THIS WEEVIL

Hi all,

I live in Panama and have a big garden with around 200 species of
heliconias. Our co-ordinates are around 8.5 and -82.5 and the elevation is 1400 metres.

Just recently we have begun to notice the weevil in the attached photos
boring into the stems of heliconias. The bright yellow weevil is about 1.5 cm long. The other picture is an
immature weevil, just over 1 cm.

I have searched Google for a few days; both the web and the image
search features. I have also tried some bug key but so far no luck.
Any help appreciated.

Regards,

Angel
