Feed A Mosquito Mosquito Eggs: Confirmed Eggs and What They Do

In Feed A Mosquito, mosquito eggs are the reason boss fights exist. The game's own How to play notes lead with "Fight with Boss Mosquitoes for mosquito eggs," listed ahead of feeding and base upgrades. Every egg follows the same verified path: it drops as a ground pickup after a Boss Mosquito dies, hatches on your base plot into a named mosquito, and that mosquito pays cash per second once you feed it to 100%.

This page is a reference to the eggs themselves — what they are, how to tell drops apart, and what an earned egg does. If you want the fastest way to keep them coming, that route lives in the egg farming guide.

Where eggs come from

Eggs enter play through boss combat. You attack a Boss Mosquito and keep hitting until its health, shown at the top of the screen, reaches zero. Several larvae then fall on the ground, and you pick one to keep. Two details make this loop friendlier than it sounds:

• In the first area, every drop is common, so any pickup is as good as another.
• Larvae from other players' kills can be grabbed by anyone. Stronger players fighting nearby effectively leave shared loot behind you.

For the fights themselves — weapons, health and surviving hits — see the boss fight guide.

How to recognize an egg drop

On the ground the reward looks like a wriggling larva, and players use larva and egg interchangeably for the same item: "Now that we've gotten our first larva, our first egg." Recorded play never shows an official on-screen label for the pickup, so both names are treated as correct here.

Three visible cues tell drops apart:

1. Rarity callouts. First-area drops are all common. Later, a "rare egg" is called out during looting, and end-of-fight results are labeled "Epic egg, mythical, legendary."
2. Size. A notably bigger larva takes longer to become ready, which marks it as a bigger prize.
3. Color. A purple larva reads as a different mosquito that "will probably give me more money" — and it hatched into an uncommon venomous mosquito.

The interface tracks eggs too: the right-corner menu shows your equipped mosquitoes "and the eggs we can hatch there," while Money sits in the left corner.

What an earned egg does

1. Place it on your base plot. Position doesn't matter — "I think I can put it anywhere, it won't make much difference."
2. Wait out the hatch timer. The first common larva was ready in 7 seconds. Timers climb with size and rarity: observed examples include 2 minutes, 7 minutes for a mythical, 40 minutes, and 4 hours for a late-game egg. Any timer can be skipped with Robux; the price is not displayed in recorded play.
3. Open it when it's ready. "Let's open the lid" — a named mosquito emerges and can be placed in your base.

The same open-a-ready-egg interaction repeats across both recorded playthroughs, so this is the standard loop for every egg, not a one-time event.

Mosquitoes recorded hatching from eggs

These are hatches actually shown in recorded play, with the pay values displayed at the time — not an official payout table, and not a complete species list. The game shows no drop odds or fixed rarity chart, so judge each drop live by its rarity callouts, size and color. The hatched roster is compared further in the mosquitoes list.

From hatched egg to income

• The hatched mosquito attaches to you and drains your blood while you feed it. Your health regenerates automatically, so feeding costs time at your life-gainer rather than permanent health.
• Feeding raises a percentage toward 100%. Pay starts at a low share of the mosquito's maximum — "if it pays 100, it will start by paying 10. So we will have to feed it to be able to get the maximum out of that mosquito."
• At 100% fed, the mosquito pays its full cash per second. Feeding costs blood, so keep it topped up — the how to get blood guide covers the supply side.
• Money is not deposited automatically. Walk over the green circle on your base to collect it.

Late-game eggs follow the identical loop but demand a bigger blood pool: the Kraken mosquito, worth a recorded 4 million per second, drained more blood than the player could supply even after a 1-million-health upgrade. Grow your health and income before committing base slots to the biggest eggs.

Worth knowing before you place eggs

• Base slots are finite and the plot fills up as your collection grows, but it can be expanded — see base upgrades for the life-gainer and plot progression that keeps feeding sustainable.
• Because every egg hatches into income, there is no bad time to place one: open the cheap 7-second eggs immediately, and let the multi-hour timers run while you play.

To keep eggs flowing, repeat the boss loop in stronger areas for better drops — the egg farming guide maps that route out.
