Insect and Disease Identification Thread

Thank you @mamuang. The information at that link is really helpful. I am really bad at insect damage and disease identification, and NH Ext had a lot of information all in one spot, which is very helpful. From the looks of my only two apples, I can probably say with some certainty that I will have significant insect pressure in my orchard! :confused:

i recently grabbed some very old cedar fencing to use as an accent wall and am going to debug with borax in a sprayer. I noticed this little insect in abundance, anyone have a guess?20201110_105314

This is a fly and not a moth.

I have a couple different questions.

First, some of my dormant apple trees have this grayish film on some stems. It wipes right off. I started wondering what it is and if it is problematic in any way. I can’t find similar pictures when i do a search. Any ideas?

Next… Some of my plum trees have leaves that appear to be folded and stuck to the stems. I noticed this all winter but kept forgetting to ask about it. I don’t find what insect does this but probably because I am not using the correct search words.

The apple is normal (some varieties are fuzzy on young growth) donelt know about your plum

Thanks @Carlin. That’s what I thought initially, but then started to wonder about it since not all of my apples have that. I didn’t want to be overlooking a potential problem.

I don’t believe either to be a problem. To me the plum leaves just look like ones that didn’t fall off in the fall and have shriveled up.

Thanks speedster, that’s what I thought initially, but they are actually very sticky and you have to peel them off. This is unlike a dried leaf that would just break of easily, so I suspected a nasty bug of some sort.

These look like Aphids,so don’t an need ID for them,that were on a Citrus.My question is,since I haven’t studied their life cycle.Do they go through a shedding of an exoskeleton,as what it appears to be in the photo?

Yes, they molt.

3 or 4 moultings per aphid.

Found this insect last fall on my young golden russet apple tree. At the time I assumed it was some sort of wasp, but now I am thinking it was actually a moth. Hopefully it isn’t some sort of borer? I have an old apricot tree and plum tree both with peach tree borer symptoms.

Yes,a Hornet moth or Hornet clearwing.I have never met one,but probably might think about leaving the thing alone,if that happened.Which is what the disguise is designed to do,as defense.

It is a sesiid, or clearwing, moth.
The moth commonly known as a hornet clearwing is only in New England.
There are several moth species very similar to the ncguire moth that are more local to New Mexico, this one for example:

(there were several other similar moths for NM also)
These various species all tend to specialize on what they bore into, you may have to check with a local extension agency to see if they are familiar with your particular moth.

Not sure if this pale spot on my apricot is a problem or not, but it’s noticeable from across the yard. It’s not even all the way around. I do suspect it might be related to what’s fairly obviously insect damage on one of the branches.

I haven’t scratched the bark yet to see what it looks like underneath. It’s also about where I’m planning to make a heading cut, so it might go away either way?

It looks like lack of uv and you had a band of tape or tree wrap on it

Aha! I did just take the stake and tie off. That would explain why I hadn’t noticed it before. Thanks!

Branch damage likely leaf or bark miner.
