This insect initially looked like a tiny ant foraging on the vastness of a footbridge handrail. It was running around and around in very small circles and did this for some time. When it eventually stopped, I took some images before it began the circling behaviour again. The insect turned out to be one of the smallest moths I’ve seen, at less than 5mm overall length. Unsure as to type of moth. Concealer?
maybe it is one of these https://inaturalist.ala.org.au/taxa/177738-Hydroptila https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/b0da9007-acf0-4230-b655-524412adcb54#gallery whatever it is, it is a stunning record!
