About the species

Pure Black Line is a pure black bee line with no Taiwan Bee genetics mixed in. The body is deep black with dense white marking and a very stylish appearance. Pure lines are sought after in breeding because the offspring are predictable.

Recommendation

Pure Black Line suits anyone who wants to build a pure black line. Keep it separated from Taiwan Bee and hybrids to preserve the genetics. Active soil, remineralised RO water and small, regular water changes give stable colour and good reproduction.
