Can't help with this insect, never seen one.
What I can offer is a little tip with egg sacks or tags of any kind.
After some use a tag or egg sack can spread around the bend. To stop this leave either the tag end of the tying thread or floss from the tag hanging out of the "back" of the tag. Once you have made the tag bring the loose end over the top and tie it down under the rest of the dressing.
Cheers,
A.
