How can I tell males and females apart?

Females are wingless and retain a nymph-like appearance even as adults. Males develop slender wings and are able to fly once mature. Checking for the presence of wings makes it fairly easy to distinguish the sexes.

How big do adults get?

Adults reach about 36mm for males and about 30mm for females, with males being slightly larger. Along with the presence or absence of wings, this size difference is another way to tell the sexes apart.

Is it true it releases a smell when startled?

Yes, that's correct. When startled or stressed, this species releases a pungent defensive secretion as a natural protective response. Handling it gently and avoiding unnecessary stimulation helps keep this to a minimum.

How difficult is it to keep?

This species is generally considered suitable for intermediate-level keepers. Prior experience with other insects or invertebrates makes it easier to manage day-to-day care and notice changes in condition.

What is its temperament like?

This species tends to be calm and doesn't display much dramatic activity that would startle a keeper. That said, it can release a pungent defensive secretion when startled, so it's best to avoid touching or disturbing it too frequently.

Ornate Velvet Cockroach

The Ornate Velvet Cockroach is prized for its striking look — a glossy black body rimmed in vivid orange-yellow — and its origins in southern Africa. Its nymphs are just as eye-catching, sporting bright orange bodies marked with black, teardrop-shaped spots, so the species' appearance shifts noticeably as it grows. Females are wingless and keep a nymph-like form even as adults, while only males develop slender wings and can fly. Calm and undemanding to watch, they do release a pungent defensive secretion when startled, so a bit of careful handling experience helps. With its bold coloration and unusual life history, this is a popular choice among exotic-insect keepers with some prior experience.

About Ornate Velvet Cockroach

The Ornate Velvet Cockroach: a black, orange-rimmed roach from southern Africa where only males fly and females stay wingless. A guide for intermediate keepers.

7 things to know before welcoming a Ornate Velvet Cockroach

1Intermediate-Level Care
The Ornate Velvet Cockroach is generally considered suitable for intermediate-level keepers. Having prior experience with other insects or invertebrates makes it easier to stay calm about day-to-day care and any changes in the animal's condition. If this would be your first exotic insect, it may be worth building experience with a hardier species first.
2Nymphs Look Nothing Like Adults
As nymphs, this species has a bright orange body marked with black, teardrop-shaped spots — a striking look on its own. As adults, the coloration shifts to a calmer black body edged in orange-yellow, giving it a noticeably different appearance. Watching this transformation unfold across growth stages is part of the appeal of keeping them.
3Males and Females Differ
Females are wingless and keep a nymph-like appearance even after reaching maturity, which is one of the species' most distinctive traits. Males, by contrast, develop slender wings and are able to fly as adults. Adult size also differs slightly by sex, with males reaching about 36mm and females about 30mm.
4A Startle Triggers a Scent
When startled or stressed, this species can release a pungent defensive secretion. This is a natural protective response, so it's best to avoid handling it roughly or jostling its enclosure suddenly. A quiet, observation-focused approach to keeping them works well.
5Growth Happens Through Molting
Like other cockroach species, the Ornate Velvet Cockroach grows by molting repeatedly. Just before and after a molt, its body is soft and vulnerable, so it's especially important to avoid disturbing it during this period. There's no need to rush to remove a shed skin — it's fine to clean it up once the animal has settled down.
6Native to Southern Africa
The Ornate Velvet Cockroach is native to southern Africa. Keeping its natural habitat in mind when setting up an enclosure helps create a more comfortable environment for the animal. It's worth remembering this is a regionally specific species rather than a widely distributed generalist.
7Prepare the Enclosure First
Before your cockroach arrives, prepare hiding spots or shelters so it can settle into its new surroundings more easily. Placing the enclosure somewhere quiet, away from loud noise or vibration, also helps reduce stress. Right after arrival, avoid handling it and instead give it time to get used to its environment.
