Lasiodora klugi Care Guide

Lasiodora klugi, usually known in the hobby as the Bahia Scarlet, is a New World terrestrial tarantula from Brazil. Adults reach about 18–22 cm (7–8.5 in) and growth is fast. Good care comes down to matching the enclosure to the species' natural lifestyle, keeping fresh water available and making small adjustments from what the spider actually does.

What to expect

Bahia Scarlets come from Brazil and are kept as terrestrial tarantulas. Adults reach about 18–22 cm (7–8.5 in), with fast growth. In the UK hobby, the species is currently best described as uncommon.

Do not expect every Bahia Scarlet to behave identically. Appetite, retreat use, webbing and confidence in the open can vary between individuals, so use the species' normal lifestyle as a guide and adjust to the behaviour of the individual spider.

Enclosure setup

Bahia Scarlets are terrestrial, so the enclosure should prioritise floor space, secure footing and a low fall height. Give the spider a snug hide at ground level and enough substrate for normal digging or rearranging around the entrance.

Keep heavy decor low and stable. As Lasiodora klugi grows, increase the enclosure gradually; a small sling does not need to be placed straight into an adult setup simply because the species can eventually reach about 18–22 cm (7–8.5 in).

Temperature and room placement

A practical temperature range for Lasiodora klugi is 21–26°C. Stable room conditions are more useful than chasing a precise number every hour. Check the shelf where the enclosure actually sits, especially during very warm weather and through winter.

For Lasiodora klugi, keep the enclosure away from direct sunlight, radiators and electronics that create local hot spots. Do not attach a heat mat directly to the enclosure; if the room is genuinely too cold, warming the room is easier to control than creating one concentrated hot surface.

Moisture, water and ventilation

For Bahia Scarlets, the moisture approach is straightforward. Keep a water dish available and maintain moderate lower-substrate moisture. Strong ventilation. You do not need every part of the substrate to be equally wet, and persistent condensation or a stale smell usually means the enclosure is staying too damp.

Keep a clean water dish available for Lasiodora klugi once the spider is large enough to use one safely. Smaller juvenile enclosures can dry faster than adult setups, so adjust how often you add water to the actual drying rate rather than following a fixed calendar.

Feeding

Feed Bahia Scarlets according to their size, appetite and abdomen rather than a fixed weekly schedule. Use established feeder insects that the spider can overpower without a long struggle, and remove live prey if it is ignored.

Young spiders usually eat more regularly while they are growing. Adults can go much longer between meals. If Lasiodora klugi begins refusing prey and spends more time hidden, premoult is one of the first normal explanations to consider.

Growth and moulting

Growth in Lasiodora klugi is fast. Young Bahia Scarlets generally moult more often than large juveniles and adults, and appetite often changes as a moult approaches.

During premoult in Lasiodora klugi, remove live prey and keep fresh water available. After a moult, leave the spider undisturbed until the new exoskeleton has hardened and the fangs have darkened before offering food again.

Temperament and safe maintenance

Individual Bahia Scarlets vary in how they respond to disturbance, so work around the behaviour of the spider you actually keep. Use long tools when useful and have a catch cup ready for rehousing.

Handling is unnecessary for routine care. Even a normally steady Bahia Scarlet can react quickly to vibration or a sudden movement, and keeping the spider inside a secure enclosure is safer for both keeper and animal.

Male and female lifespan

Male Lasiodora klugi are generally expected to live roughly 3–5 years, while females can live 15–20 years. These are broad captive ranges, not exact lifespans, and individual growth history can shift maturity earlier or later.

Female Lasiodora klugi continue moulting after maturity. A mature male eventually reaches his ultimate moult and may become more active around the enclosure while feeding less often. Keep moult dates if you want a clearer picture of age, growth and sex over time.

UK availability and naming

In the UK hobby, Bahia Scarlets are currently classed as uncommon. Availability can change quickly between specialist stock lists, captive-produced batches and show weekends, so treat that label as a guide rather than a promise that a particular size or sex will always be easy to find.

When buying a Bahia Scarlet, confirm the scientific name as well as the common name. Common names can be reused or changed in the hobby, while Lasiodora klugi is the more reliable identifier for care records and future reference.

Long-term care

Long-term care for Lasiodora klugi is mostly about consistency. Keep the enclosure secure, maintain fresh water, feed sensibly, respect the spider's retreat and make changes only when the setup stops working for the animal.

Rehouse a Bahia Scarlet when the existing enclosure has genuinely become cramped or awkward to maintain, not simply because the spider touches the walls. Prepare the new enclosure completely before moving the spider so the transfer itself can be kept short and controlled.
