Emerald cockroach

Pseudoglomeris magnificaCorydidarum magnifica

The page we cite does not state this figure. We opened it on 10 Aug 2026 and it gives no temperature for this species at all. The values above may still be right, but we cannot show you where they came from, and nobody here has checked them against a second source. Anything about a sick animal goes to a qualified exotic vet, not to a page. en.wikipedia.org

Drag the sun. Emerald cockroach is diurnal, so what it is doing changes with the light.

The way of life is written in this sheet, word for word. The climate words summarise the two figures above them, they do not add to them.

The numbers

Temperature

152025303540 °C
22–27°Ambient

One ambient band, 22–27°C. This sheet states no warm side, no cool side and no night figure, so none are shown. Same scale on every sheet here, so two species compare by eye.

The sheet states22-27C (cooler; avoid heat)

Humidity

Enclosure
Tall ventilated bioactive bin with bark; climbers - barrier + tight lid

Identity

Adult size

1520100400 cm
2.5–3 cmNose to tail, adult

The size the sheet states for a grown animal.

Why

Two drawings, because they answer two questions. The silhouette is at true scale against a 1.75 m person: it says how big this animal actually is, which no number does for someone who has never seen one. The bar under it is logarithmic and shared by every sheet here, so a 2 cm isopod and a 4 m python both stay readable on the same axis and two species can be compared at a glance.

What your climate adds

This sheet states a range to hold. Your local climate decides how much work holding it is. Pick the nearest city: nothing is sent anywhere, the choice stays in this browser.

Diet

Feeding rhythm

every 2.3–3.5 dAs the sheet states
12Meals in 28 days

Twenty-eight days, one row. Each band is a meal window.

Why

The windows widen as they go because the interval is a range: four meals after a 10–14 day cycle land anywhere between day 40 and day 56.

The sheet statesVeg/fruit + grain/protein dry feed; grazes biofilm/lichen · 2-3x/week

Behaviour and handling

HandlingDocile; active - handle over a bin
CommunalColonial - keep in groups
Defense / stress signsQuick climbing, retreat to bark

Reproduction

Life course

Day 0Hatch
1–2 yrLifespan in care
1 yrMinimum commitment
Sexual maturityNot in our data

Read from the lifespan and maturity the sheet states, for animals in care and not in the wild.

Why

The minimum commitment is the low end of that lifespan, and the reproductive window is what is left after maturity: both are subtractions on stated figures, not figures of their own.

Reproduction
Ovoviviparous (live-bearing); small, slow broods

Common health problems

Common health issues
SignsHeat death, mould, mites, dehydration
Red flags / quarantine
SignsKeep cool + ventilated; climbers escape; quarantine; never release non-natives

Good to know

  • One of the only truly metallic-green cockroaches - a living jewel that commands high prices

Not stated: The size of the enclosurethis sheet describes the enclosure without a figure: « Tall ventilated bioactive bin with bark; climbers - barrier + tight lid »

Every line above is deduced from a value this sheet states, and names which one. Nothing here is a general recommendation. What the sheet does not state is listed too, rather than left out: a kit that looks complete is worse than one that names its gap.

What this sheet states

85%
TemperatureHumidityEnclosure sizeActivityOriginDietSourcesUVB

This sheet states 6 of 7 of the fields this product runs on. What is missing turns something off: enclosure size audit. We show the gap rather than fill it with a plausible number.

UVB is measured but does not count: it is absent from 421 of 678 sheets, and on most of them that is not a gap, since a nocturnal snake's sheet has no reason to state a UV index. Counting it would call the library incomplete without cause.
