Looking for a trustworthy shop for rare and exotic invertebrates in the UK? The short answer: choose a specialist seller that breeds or sources its own stock, identifies every species accurately, packages live animals properly for the post, and stands behind arrivals with a guarantee. This guide explains exactly what to check before you buy — and how we do things at PostPods.
First, an Honest Correction: Most "Rare Insects" Aren't Insects
The hobby talks about "insect shops", but the most sought-after exotic species in the UK invertebrate hobby are mostly not insects at all. Isopods are crustaceans, millipedes are myriapods, and tarantulas and jumping spiders are arachnids. True insects — beetles, cockroaches, stick insects — are only one part of the picture.
That distinction matters when you're buying, because each group needs different housing, humidity and food, and a shop that blurs them together is a warning sign in itself. A good specialist will tell you the correct scientific name for every animal it sells and won't promise one-size-fits-all care advice.
What Counts as Rare and Exotic?
In the UK hobby, "rare" usually means one of three things: species only recently brought into culture, locality-specific lineages with documented origins, or established species in colour forms that are hard to find. Some current examples from the isopod side of the hobby:
- Ardentiella (formerly Merulanella) — vividly coloured Southeast Asian isopods that were almost unobtainable in the UK a few years ago and remain genuinely scarce.
- Cubaris — the genus behind the famous Rubber Ducky and its many locality variants, where documented lineage is a large part of what you're paying for.
- Less common genera such as Fillipinodillo, Troglodillo and Ignama — small, specialised groups kept by relatively few UK breeders.
Beyond isopods, the exotic invertebrate hobby covers millipedes, cockroaches, springtails and more — you can browse the non-isopod side of our range in other inverts for sale.
How to Judge a Shop Before You Buy
Accurate species identification
Every listing should carry a proper scientific name, and where lineage matters (as it does with many Cubaris), the origin or bloodline should be stated. Vague listings like "mixed tropical isopods" make it impossible to know what you're getting or how to care for it.
Captive-bred, established stock
Captive-bred animals from established colonies are hardier, better acclimatised to UK conditions and more sustainable than wild-caught imports. Ask where stock comes from — a good seller will be happy to tell you.
Proper live-animal packaging
Live invertebrates should travel in ventilated containers with damp substrate or moss to hold humidity, padding to limit movement, and insulation against temperature swings. Shipping days matter too: animals shouldn't sit in a depot over a weekend. At PostPods we post Monday to Thursday only, whatever postage method you choose, so nothing is left in the network over the weekend.
A guarantee that means something
Reputable UK sellers offer a live arrival guarantee — if something goes wrong in transit, you're covered. Check the terms before ordering and photograph any problem on arrival, unopened where possible, so the seller can put it right quickly.
Real knowledge behind the counter
A specialist shop should be able to answer species-specific care questions before you buy, not just process orders. If you're unsure whether a species suits your setup or experience level, ask us — talking someone out of an unsuitable purchase is better business than a dead animal and a disappointed keeper.
Caring for Rare Species Once They Arrive
Rare doesn't always mean difficult, but it does mean less room for error — replacing a lost colony of a scarce species can take months. Three principles cover most situations:
- Research the species, not the group. "Isopod care" or "millipede care" is a starting point, but humidity, temperature and diet vary properly between species. Set up the enclosure before the animals arrive.
- Quarantine new arrivals. Keep new stock separate from established colonies for a few weeks. It protects your existing animals and lets you watch the newcomers settle.
- Start colonies, not individuals. For isopods and other colony animals, buying a proper starter group gives a far better chance of establishing a breeding population than one or two specimens.

If you have a question about any species before or after you buy, we'll give you a straight answer — including telling you when a species isn't the right fit.
Frequently Asked Questions
What should I check before buying rare invertebrates online?
Look for accurate scientific names on every listing, captive-bred stock, a live arrival guarantee, sensible posting days that avoid weekend delays, and a seller who can answer species-specific care questions before you order.
How are live invertebrates shipped safely in the UK?
In ventilated containers with damp substrate or moss for humidity, padding to prevent movement, and insulation against temperature extremes. Reputable sellers post early in the week so animals never sit in a sorting office over the weekend.
Are isopods insects?
No — isopods are terrestrial crustaceans, related to crabs and shrimp. Millipedes are myriapods and tarantulas are arachnids. "Insect shop" is used loosely in the hobby, but most exotic invertebrates kept in the UK aren't true insects.
What makes an isopod species rare?
Usually one of three things: it's new to culture, it's a locality-specific lineage with a documented origin, or it's an established species in a hard-to-find colour form. Documented lineage is especially important in genera like Cubaris.
What should I do if my order arrives in poor condition?
Contact the seller straight away with photos, ideally before disturbing the packaging. Reputable UK sellers offer a live arrival guarantee and will replace or refund affected animals.
