Resin eating my yucca plant leaves??

Hi, some of the leaves on my yucca plant are being consumed by something unknown – but it leaves behind a red “resin” which turns into a solid amber-like substance. The leaves are slowly dying off but I have no idea how / why / what it causing it!

Please see the images attached which should be useful.

Thanks for your help!
