thanks, martinl. I'll check.

Thanks for your comment, sintija.valucka. The silk thread that appears in the video was produced by the time I was taking the pictures. I moved the leaf up down several times to find a good angle for pictures, then the larva feel insecure and launch the silk to it be fixed on the leaf. The house is of about 1 cm, seems a tiny dead flower. You may not know that there is something living there, unless it moves. I still need to find an article about how these larvae can build their houses. I am fascinated by this little hat. :) Thanks, dear riekos. :)
