it looks pretty solid to me
just use it properly and you will have no problems with it

Well, I don't really see the need to Ant, you maybe use Hopper instead since he can destroy himself while equiped (the great goal, since Centipedes and Dragonfly get their effect when a card equiped to they is destroyed.) Also maybe consider insect Imitation and a third lady bug? easy way to bring your Dragonfly/Hornet to the field/Graveyard, Deck devastation virus works on the deck in case you'd like to use it, Dark Armed Dragon is a beast on this deck too (since you can easyly control how many dark monsters you have on the graveyard with inzektors effect), his effect is way too good too, just a problem on tags when your partner think that is good to use your Hornet to activate his effect lol.

Inzektor Ant is basically a shield for centipede or Dragonfly while triggering their effects while saving themselves for destruction.

Yep, but with Hopper you could use a Hornet + Insect imitation to use Hornet effect instantly, instead of ant you could use 3 Call of the Haunted to revive Centipede and Dragonfly, I mean, you have many ways to revive they, it's a die hard deck, Equip Giga-mantis+Hornet to any inzektor, destroy giga-mantis, bring back any inzektor to the field or just leave a monster with Inzektor Sword - Zektkaliber and recycle to any inzektor to hand.

Just a little thing to speed up the deck, is not really necessary (Hopper), but well, for me having 3 lady bugs and insect imitation increase the consistency of the deck since you can use it to bring Centipede, and add any inzektor to your hand (Since you can equip and use Ladybug blahblahblah), or even better, dragonfly and centipede to make a Rank 5 monster, just by having insect imitation and ladybug on hand, Hopper was just a good alternative to have an use for insect imitation while you have no ladybug on hand.
