Even without fire type moves, Larvesta's stats (higher attack than karrablast) and movepool (access to plenty of non fire type moves) and even flame body make it unsuitable for this format.
Updated team building rules. Please read them carefully as the list is different from some of the ones that have been posted.
There's a reason why all the Limited pokemon are limited! They are quite overwhelming compared to the weaker bugs, and with boosts, basically end up being unstoppable sweepers. However, keep looking at the options available!
I would like to point out Shelmet. He is Limited now but he has incredible checks to the sweepers: very good movepool and great defense.
It can use Acid Armor, Curse, Toxic, Recover, Substitute(banned currently), Baton Pass, Yawn, Spikes, Encore - all of these tools are going to be beneficial to a team. Also, with Hydration, it can set up Rain Dance to deal with opposing pokemon trying to beat it with status, although that could be risky if facing a surskit.
Note that a x2 aerial ace is still weaker than a STAB Megahorn, and the same power as a stab X Scissor
All the baton pass - available pokemon are Semi limited except for the stronger ones (Shelmet, Sewaddle) are Limited. Boosting moves in general are the big game.
I have banned Substitute for the following reasons: lack of phazing, incredible stalling not in the spirit of the tier, and stuff like Iron Defense/Acid Armor already making it hard for Drones to do anything.
anyway here is my spinarak set @leftovers
Spider Web
Hone Claws
Baton Pass
Poison Jab
This is a pretty funny set that can be used to trap a Drone and set up on it. Poison Jab gets STAB and 30% poison chance.
Note that Bug and Poison both hit Bug neutral, Grass super effective, and Poison not super effective. The difference is Bug hits Flying not super effective and Poison hits neutral.
