I use PVA glue, it has the advantage that it sets clear and will pull the torn sides together as it dries. It is also water-soluble which can be both an advantage and disadvantage depending on circumstances.

I will generally place two small drops of white glue on a small strip cut from a note-card and use it (or a few of them, depending on the size of the repair) to splint the wing. Just make sure you place it on whatever side of the wing will not be on display. I have had some very good successes with this method on various butterflies and moths. The smallest specimen I have used it on was Utetheisa ornatrix (bella moth). From above the repair is unnoticeable. Hope this helps.
I realize you've most likely already repaired your wing tear. Just had to share my thoughts on this. I have found that mixing 50% Elmer's glue with 50% Isopropyl alcohol works great. The glue is more liquid/easy to spread and not globby, and the alcohol evaporates leaving a very thin film of glue when dried.
I am a big fan of minimal glue when gluing a specimen. Globs of glue do not appeal to me. Lastly, should you ever desire to re-work the wing, softening it will loosen up/unglue the repair glue on the wing. Some of the permanent glues do not ever get undone and one is stuck with whatever that moment created repair-wise.
I have yet to know a fellow bug man who tried it and didn't like it

The problem with some of these glues is that sometimes they dry with a milky tinge.
Crayola 3D Project Glue (also white glue) dries completely clear and seems to stick better to insect parts than some of the other ones I tried. I use it for the antennaes where I don't want a film of glue showing in between the butterfly eyes
with Crayola the antennae stays stuck for good, with Elmers it can fall off again
I use the same technique as entoman, but I use plastic model airplane glue (because I used to build lots of plastic model airplanes and I'm familiar with how it dries). I've tried Elmer's, but it sometimes causes the wing to curl as it dries. Mixing it with alcohol sounds like a good idea. Instead of note cards I use regular computer paper because heavy paper can cause another wing tear.
I use egg white and a small amount Isopropyl alcohol. Shake well before use. I use small laboratory test tubes with a real rubber stopper. Shake well before use. I have a #2 stainless steel insect pin embedded in a 1/4 inch dowel rod.
Lick the pointed end of the pin in the dowel rod. Dip the pin in the mixture, slide the damp pin with the mixture on one side of the slit. I primp the area with a dry pin. Works 95% of the time for me.
