琥珀的奇幻世界

足絲蟻是只有8科的小家族，前腳有絲腺，會泌絲結網來保護族群不受獵食者的攻擊。雖然以樹幹為居所，但在琥珀中卻非常罕見，體長介於在5~8 mm之間，雌蟲無翅，易被誤認為白蟻；其前足第三跗節明顯澎大，是辨識重點。

Web spinners are a small order with only 8 families. With silk glands, their forelegs can secrete silk to make a web for protecting their group from predators. Although they live on tree trunks, it is very rare to find them in amber. Their body length is between 5-8 mm. The females have no wings and could be mistaken for termites. The third tarsus on their foreleg is distinctively enlarged, a clue for identifying.
