Hello all, I have been readin this forum for many years now and i love my little trees. Most of the time i can find my bugs online and how to not have bugs any more. well today i was at a friend's house looking to scout out an azalea an air layer-ing and I came across an odd bug. maybe an egg sack? its soft and white fluffy but juicy stuck to the branch. it doesn't seem to be scale. almost like it was held in place by this fluff. seems 'bout 6-8mm long and 'bout 4 or so thick. any ideas?

thanks, reddog

That looks like a cocoon. It could be a harmless butterfly or a moth, either way the larval form is the one that normally eats the leaves of your tree, after hatching they will fly away to lay eggs elsewhere.

I think it IS scale. There are lots of different kinds. Just squish it.

it does look like a cocoon, however there are many but not like a scale problem. on the idea of scale, they do not seam to be affecting the health of the tree. eggs maybe?

That could be a cottony azalea scale. Once I switch to "reply" mode, I can no longer see where a person is from, so, Reddog, this is most likely to be the case if you live in MD, NY, FL, AL, VA, or NH.

Cottony azalea and cottony maple scales will be two different critters. Anyway, squish them or use a pyrethrin spray.

It isn't Cottony Maple Scale, there's a picture of that on our rogues gallery here https://ibonsaiclub.forumotion.com/bonsai-pests-diseases-f9/rogues-gallery-with-a-few-heros-too-t528.htm - it's the 13th one down.

Cottony scales all look alike: cottony. The maple one is one maple, the azalea one is on azalea.

There's one way to find out. Carefully remove it to a jar with air holes and wait to see what comes out! Wink

That'll only work if it is a cocoon -- which is is NOT. It is a scale insect. Crush it of spray it.
