Lance is one of the best (if not THE best) weapon for SQ, and I've NEVER run out of stamina when fighting her, so maybe it's just that you're not really used to lancing.

She has a fairly easy exploit when she charges at you that leaves her weakspot open for attacks for a good 2 seconds. If she does the regular running charge at you (not fused with Seltas) and you have your back against a wall, you counter the charge preventing damage, however the SQ still has to "finish" her attack so she keeps running into the wall. Here you can attack freely without taking any damage. And since you'll be attacking the weakspot, it'll probably get you a flich, giving you an opportunity for an easy headlock.

When she calls a Seltas, there will be a long animation in which the Queen shakes the Drone and then she plants him on her back. This gives you plenty of time for climbing a wall or just getting ready for a Lance charge. When the neopterons fuse, they'll more often taunt, which is when you go for the mount. Just keep in mind though, if you opt for the Lance charge option, make sure you hit the Seltas and not the SQ. Getting one jump attack on Seltas is highly likely to get you an insta-ride, and then you can just finish him off. And even if you don't kill him fast enough, a mount will make him stop flying for a little while and wander around aimlessly, while you focus on the Seltas Queen.

When it comes to the attacks you've mentioned you have trouble with, the taunt-into-charge attack is a Desert SQ only-attack, regular G SQ never does it. For that attack where she puts her tail above her face like a scorpion, you can easily evade it by timing your backhops. It's very easy and evade+ skills aren't needed. Backhop > poke > Backhop > poke and so on.

Finally, if you're having trouble keeping your stamina, keep in mind the shield-rush attack always takes off a fixed amount of stamina, regardless of how many attacks you block during the duration of it. Also if you finish it with a shield bash, you'll start recovering your stamina instantly. Not many know that the shield rush is indeed a wonderful tool for stalling, so if a monster is enraged and taking almost all of your stamina, you can just shield rush a couple of times and you'll have your stamina bar full again sooner than you think.

...Did I just write a Lance Guide for Seltas Queen?
