Considering Insects are loaded with deck searching, and how incredibly easy it is to gather both Cocoon and Petit Moth, Petit moth is actually playable. Add to it, it being not being a full Nomi means that after it gets Summoned, it can even be cool Junk Synchron fodder, a Debris target, hell, even Limit Reverse.
So while the other moths take a hell of a lot longer to play because of turn-counts, this card actually serves as a vital part of the main concept that the Moth series has, as well as becomes an amazing card in games like Reshef of Destruction, due to the fact Moths literally "evolve" in that game. Furthermore, there are plenty of other cards that are weaker, if not, more un-playable just because of the fact they need more materials/resources for less of a payoff(Shining Dragon, for example). Larvae Moth at least gives you a stronger version of Petit Moth, so in the long run, it could actually pay off.

tl;dr I tried to justify this card not being completely useless.

Moth was an awesome concept, but you're better off betting on a LV monster.

Well, Larvae Moth's ATK was the equivalent of today's 2000 back when the "Volume" series where the only cards around. You know, everything with more than 1000 ATK needed Tributes.

Or you could run Basic Insect for 1/3 the deck space, AND Normal support.
...I'm sorry.
