Don't know if insect related - Celticecis aciculata

Don't know if insect related - Celticecis aciculata
Theriot, Terrebonne Parish, Louisiana, USA
July 3, 2008
These were found under a leaf, and on several other leaves on the same plant

Change in identification
Celticecis unguicula is now considered a synonym of C. spiniformis, but I think this is actually the newly described species C. aciculata.

Moved from galls. Identified from an illustration in this book.

Plant species
is important in identifying galls. These remind me of galls I found recently on hackberry leaves, which it looks like your leaves may be. Many species of psyllids make galls on hackberry, so that would be my guess--if this is in fact hackberry. If it's not, these might be from some other aphid-like insect. They look more regular than mite galls to me. (I'm not a gall expert, but I've been working on figuring a lot of them out lately.)

The slender shape, gently rounded base, and especially the untoothed margin of this leaf identifies it as Sugarberry (Celtis laevigata), a congener of Hackberry (C. occidentalis) (which has a toothed margin).

Thank you for your time.
Thank you for your time.

Reminds me of the
galls that mites of the family Eriophytae produce.

must be related--
many insects chemically induce plant tumors ['galls'] to provide food for their young [young develop inside]. an expert [i'm not] could tell which insect is the culprit based on galls' shape, etc. features
Update: MY BAD, i forgot about mites, i did'n mean to discriminate and humbly ask both the mislead Requestor and Acari to accept my sincere apology :-[

Glad I found this site. Your team is a lot of help to me as a novice. As soon as I can talk my wife into it I will make a contribution to the cause.
