I found abt 15 pathches of these eggs under the leaves of my avocado tree. In the past month I have seen a similar patch of eggs (not sure if the same) hatch worm-like bugs which seem to use silks to drop off the leaf. The worms were about 1-2 mm in length. These patches continue to be placed. Rather aggressive laying habits so it must be a relatively bigger bug, possibly one that flies bc it happens overnight and on leaves top to bottom.
