SOLVED. YA Horror: Isolated island with rare killer insect [s]

[Scribblingsquid]

A man is invited to an island where an expert on insects is studying an insect. I think it may have been a butterfly or moth, possibly golden. The insect gets free and goes on a rampage. I think it may have eaten flesh/cocooned people. I think the cover had a dark background with a gold image of the insect.

Scribblingsquid, what is the hero's job - e.g., journalist as in
The Hand of the Devil by Dean Vincent Carter?
