A month ago Twitter was buzzing with news of Brood X cicadas. People were eating them, posting pictures of them, requesting gifts of them for their child’s pinned insect collection, and I was wondering how far north I would have to go to see them. Brood X cicadas are amazing in many ways as I first discovered 23 y ago when I cloned microsatellite markers from Magicicada and found them to be so beautifully polymorphic that they were useless as population genetic markers. More recently, the scientific community has been left in a state of wonder by the discovery that the genomes of Hodgkinia, the bacterial endosymbionts of Brood X cicadas, have split into more than 20 different circular molecules that are maintained as multiple distinct genomic and cellular lineages (1).

一个月前，Twitter 上充斥着 Brood X 蝉的消息。人们在吃它们，张贴它们的照片，为孩子的昆虫别针收藏索要它们的礼物，我想知道我必须去北多远才能看到它们。Brood X 蝉在许多方面都令人惊叹，因为我在 23 年前第一次发现时，我从Magicicada克隆了微卫星标记，发现它们具有如此美丽的多态性，以至于它们作为种群遗传标记毫无用处。最近，科学界因发现霍奇金亚属的基因组，即育雏 X 蝉的细菌内共生体，已分裂成 20 多个不同的环状分子，这些分子被维持为多个不同的基因组和细胞谱系而感到惊讶。 ( 1）。
