Observation Notes:
It flew around my backyard for a minute then landed on a coco coir pole then flew and landed on my leg. I allowed it to crawl onto my finger before it flew onto the screen curtain by the door where it sat for 10+ minutes. This one appeared to be slightly larger than the first one I observed in my previous record. I did take a short video; if you’d like me to send it, please let me know.
