I think it’s a moth
I just took this picture of a moth that has a fuzzy tail that was swinging back and forth very slowly with each of the little hairs moving as the tail moved. At first I thought there was a spider on the end of the moth until I got my nose up close. It measured about 3/4″ from wing tip to wing tip. I live in the Yucatan very near the border with Belize. Sorry the picture quality isn’t better.
Luckily, in the case of getting your moth identified, insects do not respect international borders. Quite fortuitously, the first page we opened in our archaic Holland Moth Book revealed a plate of 60 moths including your little Glyphodes hyalinata. We had no common name. We located a mention on BugGuide, but no image. More web searching turned up no images, but we were led to a site, the Moth Photographer’s Group from the Mississippi State University Entomological Museum. It pictured two other moths in the genus Glyphodes, but not your moth. Your moth was pictured further down the row under a different genus, Diaphania hyalinata. So, there was some reclassification of the genus after Holland’s book was published. There are some nice live images of your moth which goes by the common name Melonworm Moth. Retro-searching BugGuide with the new information gave us a hit and the following information: it is in the Family “Pyralidae, and the caterpillar is a pest of cucumber, melons, pumpkins and squash.” Identifying your species has lead us to a wonderful new website, the Moth Photographers Group.
