How fast does it grow?
Brazilian Salmon Pink Birdeaters are generally described as fast growers. That gives a useful expectation for Lasiodora parahybana, but it is not a promise that every sling will reach the same size at the same age.
Adult Lasiodora parahybana reach about often 20–25 cm; very large individuals can approach 28 cm (8–11 in). The time taken to get there depends on sex, feeding, temperature and ordinary individual variation.
Moult intervals change with age
Small Brazilian Salmon Pink Birdeaters often moult more frequently because they are growing rapidly. As Lasiodora parahybana gets larger, the interval between moults normally becomes longer.
Do not treat a longer interval in an older Brazilian Salmon Pink Birdeater as a problem by itself. Look at appetite, body condition, retreat use and the spider's previous moult pattern.
Feeding and temperature
Feeding influences how quickly Lasiodora parahybana grows, but there is no benefit in keeping the abdomen constantly overfilled. Offer suitable meals and let appetite guide the interval.
A practical temperature range for Lasiodora parahybana is 21–26°C. Stable conditions are preferable to pushing the temperature upward in an attempt to force faster growth.
Male and female growth
Male Lasiodora parahybana usually mature sooner and have a shorter lifespan of about around 5 years, while females can live up to about 15 years. That difference means two similar-sized juveniles may eventually follow very different timelines.
Sex cannot be judged reliably from growth speed alone. Use a suitable moult when possible instead of assuming a faster-growing Brazilian Salmon Pink Birdeater must be male.
Tracking growth
Record moult dates for Lasiodora parahybana and note approximate size when rehousing. You do not need precise measurements after every moult; a simple record is enough to show whether the spider is growing steadily.
Photographs taken after a Brazilian Salmon Pink Birdeater has hardened can also help show changes over time, provided the spider is not disturbed simply to get a measurement.
When growth means rehousing
Rehouse a Brazilian Salmon Pink Birdeater when its current enclosure no longer gives enough retreat space, substrate or safe access for maintenance. Do not move Lasiodora parahybana after every moult automatically.
Prepare the larger enclosure before the transfer. The goal is to keep each stage of Lasiodora parahybana's growth in housing that is secure and practical, not to race toward the adult enclosure.
