Springtails are named for the little forked lever tucked under the abdomen that catapults them out of trouble. Orange springtails have largely given up on it. They crawl instead, slow and deliberate, in a colour somewhere between apricot and traffic cone, which makes them both far easier to work with than a culture that pings across the room every time you lift the lid, and the only springtail you can actually pick out by eye in a planted enclosure.
Introduction
These are Yuukianura aphoruroides, a member of the Neanuridae, sold as Orange Springtails and sometimes as Asian Orange Springtails. They are larger and considerably chunkier than the standard white springtail, reaching around 4 mm, and unlike the white Collembola most keepers start with they are genuinely visible. One honest caveat on provenance: hobby sources disagree about where the cultures in circulation originated, with some listing them as Asian and others as Spanish, so rather than pick a side we would simply say the captive requirements are well understood and the origin label is not. They also get muddled with two other species in the trade, the red Bilobella braunerae and the Florida orange springtail, both of which are different animals.
What they do
Two jobs, and they are good at both. As cleanup crew they graze mould, decaying plant matter, animal waste and leftover food, which in practice means they keep a bioactive enclosure from turning fuzzy and stop your isopod bins souring around uneaten protein. Any of the tropical species in our isopod range benefits from a culture running underneath them, and the pairing with dwarf whites makes a complete micro cleanup team for smaller setups. They also serve as a supplemental live food for dart frogs, froglets, small geckos and other micro-insectivores, though they should be part of a varied diet rather than the whole of it, since a springtail cannot be dusted with supplements the way a larger feeder can.
Care
About as low-maintenance as livestock gets. A small tub with a secure lid and a few ventilation holes is all the housing they need, with 2 to 3 cm of damp substrate in the bottom. This is the one place where coconut coir genuinely earns its keep: a springtail is not eating its way through the floor the way an isopod or millipede does, so coir, charcoal or a simple soil-based mix all work well, and coir holds moisture beautifully. Keep it damp at all times rather than letting it dry out, since drying is the usual way a culture is lost, and normal room temperature suits them across the year. A piece of bark or a few leaves on the surface gives them somewhere to congregate and makes harvesting easier.
Feeding
Small amounts, often. They will take brewer's yeast, springtail food, a few grains of rice or a scrap of mushroom, and they graze whatever mould appears in the meantime. The single biggest mistake is generosity: overfeeding a culture fouls it and can crash the colony outright, so put in less than you think and add more once it has gone. Feed a little and they multiply steadily and quietly.
Harvesting
Because they do not jump, getting them out is far simpler than with white springtails. Lift the bark they have gathered on and tap them straight into the target enclosure, or flood a corner of the culture with a little water and pour the floaters off. Take a portion and leave the rest to rebuild, and a healthy culture will keep producing indefinitely.
Who is this for?
Anyone running a bioactive setup, and especially anyone who has been frustrated by white springtails scattering the moment the lid comes off. They suit dart frog and small reptile keepers wanting a live supplemental feeder, isopod keepers who want mould under control in their bins, and planted terrarium owners who would rather their cleanup crew was visible than invisible. About the only keeper they will not satisfy is someone after a fast, jumping species. For everything they pair with, browse our springtail range, our best-selling Rubber Ducky isopods, and the substrate and botanicals in our accessories range, including flake soil.
Cultures leave us established and productive rather than freshly split, travelling in their own substrate under our live arrival guarantee. Dispatch runs Monday to Thursday on Royal Mail next day before 1pm, keeping every culture out of the weekend post.
