Definition
The collective noun for a group of lemurs — ring-tailed lemurs in particular are highly social, communicative, and known for their mischievous, inquisitive behaviour.
Beyond the definition
Anyone who has watched lemurs knows the name is earned. They huddle, they whisper (vocally), they glance sideways. They have the energy of a group planning something. A conspiracy of lemurs is funny because it's true.
Origin & history
From Latin conspirare — to breathe together, to plot (con- 'together' + spirare 'to breathe'). The collective noun reflects the lemur's tendency to gather in tight, communicative groups that do look, uncannily, like they're scheming.
