Every Feed A Mosquito egg tier in order, what rarity actually changes, how to measure an egg's income yourself, and which hatch deserves your blood first.
Feed A Mosquito Egg Rarity: Tiers, Odds and What to Feed
Egg rarity is the most talked-about and least documented system in Feed A Mosquito. Fan sites list five or six tiers, throw around a "0.001%" mythical figure, and then admit in the next paragraph that the developer has never published drop rates. The result is a genre of guide that sounds precise and teaches nothing.
This page does the opposite. It gives you the tier order the community agrees on, marks exactly which claims are unverified, and then hands you a measurement protocol so you can rank your own eggs in ten minutes instead of trusting a number someone invented for search traffic.

What rarity actually changes
Confirmed by the official description and the in-game loop:
- Rarer eggs come from harder content. The developer's line is "fight boss mosquitoes for eggs", and the community consensus is that deeper bosses drop better eggs.
- Every egg hatches into a mosquito you can feed. Rarity does not skip the feeding step.
- A fed mosquito generates cash. Rarity is the main visible variable in how much.
Not confirmed by anyone:
- Exact drop percentages per boss.
- Exact income multipliers per tier.
- Whether rarity affects hatch time independently of egg size.
- Whether there is a pity system, duplicate protection, or fusion.
That gap is why this page focuses on method. A tier list you cannot verify is entertainment; a measurement you ran yourself is a decision.
The tier order
| Tier | Visual tell | Hatch time | Income | Feed priority | Confidence |
|---|---|---|---|---|---|
| Common | Small, plain egg | ~7 seconds (community) | Baseline | Last | High — seen constantly in the first area |
| Uncommon | Slightly larger, tinted | Longer than common | Above baseline | Low | Medium — naming varies by site |
| Rare | Larger model, distinct color | Noticeably longer | Clearly above common | Medium | Medium — widely reported |
| Epic | Large, animated glow | Long | High | High | Medium |
| Legendary | Very large, strong effect | Very long | Very high | Very high | Low-medium — few captures |
| Mythical | Rainbow or animated special | Longest | Highest | Highest | Low — "0.001%" is community folklore |
Three honest caveats:
- Names are not standardized. Some sites use "uncommon", others jump from common to rare. The order is stable; the labels are not.
- Hatch times scale with egg size, which correlates with rarity, but nobody has published a per-tier table.
- The 0.001% figure is not a drop rate. It appears in promo art as a flex, and fan sites have reused it as if it were data. Do not plan around it.
How to read an egg before it hatches
You have four signals, in order of reliability:
1. Egg size. Bigger model, better tier. This is the most consistent tell across every capture and every fan site.
2. Color and effects. Plain → tinted → glowing → animated. The more visual noise, the higher the tier. Rainbow effects sit at the top.
3. Hatch timer. Longer wait usually means better egg. Community reports put a common at about seven seconds; anything substantially longer is worth watching.
4. Source boss. Deeper boss, better pool. If you got it from the entry boss, assume common until proven otherwise.
None of these is a substitute for the income number after feeding, which is the only thing that actually pays you.
Measure your own eggs: the ten-minute protocol
You need one hatched egg, a stopwatch, and a consistent feeding routine. Run this for each tier you own.
Step 1 — Record the hatch. Start the timer when you place the egg, stop when the mosquito appears. Write it down. This is your hatch-time baseline for that tier.
Step 2 — Feed to exactly 100%. Same seat, same starting health if possible. Note how much health the feed consumed. You can read this from the bar before and after.
Step 3 — Collect for five minutes. Do not upgrade anything during the test. Stand at the base and collect every pickup. Total the cash.
Step 4 — Divide. Cash ÷ 5 = cash per minute at 100% feed. That is the number that matters.
Step 5 — Repeat three times. One sample is noise. Three samples on the same egg tells you whether the rate is stable.
Step 6 — Compare across tiers. Same protocol, different egg. Now you have a real table:
| Egg tested | Hatch time | Blood to 100% | Cash in 5 min | Cash/min | Notes |
|---|---|---|---|---|---|
| Your common | Control | ||||
| Your rare | Compare | ||||
| Your best | Decide |
Fill those cells with your own numbers and you will out-inform every guide online, including this one.
The feed-priority matrix
Blood is scarce. Eggs are not. That mismatch is the whole game.
| Situation | Feed this | Reason |
|---|---|---|
| One egg, any tier | That egg | A fed common beats an unfed legendary |
| Common vs rare, one feed's worth of blood | Rare | Higher ceiling per blood unit |
| Rare vs epic, both fresh | Epic | Same logic, one tier up |
| High tier but you are about to log off | The highest tier you can finish | Partial feeds waste blood |
| Limited event egg vs your best permanent | Event egg if it will be removed | Scarcity beats a marginal rate gain |
| Duplicate high tier | The one with the better measured rate | Two samples beat one label |
The rule underneath the table: blood goes to the egg with the best cash-per-blood, not the best color. If your rare measures worse than your epic, the label is lying to you or your sample is too small.
Where each tier comes from
| Source | Typical result | Notes |
|---|---|---|
| Starting field | Common | The first area's pool is reported to be common-only |
| Entry boss | Common to rare | Your first upgrade path |
| Field boss | Rare to epic | Where most mid-game players farm |
| Deep-field boss | Epic and up | Requires a real build |
| Space Zone | Unconfirmed | V3 area; no drop table exists |
| Halloween event | Limited mosquitoes | Confirmed as a feature; details land October 26 |
The Space Zone is the big unknown. Community sites report that V3 added it; the official description does not mention it, and no fan site has published a verified drop pool. If you are farming there, log your drops — you are generating data nobody else has.
What rarity does not do
It does not remove the feed step. A legendary egg still needs 100% blood. If you cannot afford the feed, the legendary is a decoration.
It does not guarantee a better income per blood unit. Hatch time and feed cost may scale with tier. A high-tier egg that takes three times the blood for double the income is worse in the early game.
It does not make commons worthless. Commons are fast to hatch, cheap to feed, and replaceable. Early on, three fed commons can out-earn one unfed rare.
It does not protect you in PvP. If the PvP zone works the way fan sites describe, an unhatched egg is loot. Rarity makes it more attractive, not safer.
Should you chase the mythical?
Only if you already have a stable loop. Chasing a 0.001% roll before your base produces steady cash means hours of bossing with nothing to show. The efficient order is:
- Stable commons producing cash.
- One rare or epic fed to 100%.
- Upgrade the base until the loop is fast.
- Then farm deep bosses for high tiers.
A mythical is a lottery ticket. The base is the salary.
Halloween limited mosquitoes: what to do with your eggs now
The official description confirms new limited mosquitoes for the Halloween update. Limited usually means time-gated, which changes egg strategy for the next few days:
- Bank blood, not eggs. Blood carries into the event; an unhatched egg occupies a plot you may need.
- Leave one plot free before October 26 so an event egg can hatch immediately.
- Do not dump your best egg into a feed you cannot finish the night before the update.
- Screenshot your current income so you can tell whether the event units actually beat your baseline.
Event units are often sidegrades with a scarcity premium. Measure before you rebuild your base around one.
FAQ
How many egg rarities are there?
The community consistently uses five to six tiers: common, uncommon, rare, epic, legendary, and sometimes mythical. The exact official list has not been published.
What is the rarest egg?
Mythical, if the tier exists, with rainbow visuals. The "0.001%" number attached to it is promo copy, not a confirmed drop rate.
Do higher-rarity eggs take longer to hatch?
Egg size and hatch time correlate, and community reports say bigger larvae take longer. There is no published per-tier timing table.
Can I get a legendary from the first boss?
Unconfirmed. The first area is reported to drop commons, and tier pools widen as you go deeper. No verified per-boss table exists.
Should I feed a common at 100%?
Yes, early. A fed common is income; an unfed rare is potential. Switch blood to the rare once you can finish the feed in one sitting.
Do eggs expire?
No expiry is documented for normal eggs. Event eggs may be time-limited; that is a separate rule and should be treated as unconfirmed until the update notes.
