No it wasn't a discarded 80s toy, like these (though I might have been equally excited if it was):

Check out those sexy pectinate antennae!
This beauty of a specimen is a male Western Banded Glowworm, Zarhipis integripennis. I know it's a male because it doesn't glow and it isn't wormy. That's right, only the grubs and adult females (which resemble the grubs) can glow. I find it intensely odd and fascinating that these insects have evolved, such that the adult females look and behave similarly to the immature forms. Imagine what our lives would be like if humans did that! Okay, maybe not.
