Did You Know?

  • Silvery Checkerspots are investigative and aggressive by behavior. Scientists have observed them flying out at passing or moving objects, including insects, birds, Frisbees, etc. They have even been noticed leaving their flight path to observe human activities.
  • The males of the species are territorial and have been observed chasing other butterflies out of their areas.
  • During mating/reproduction, an unreceptive female will keep its wings closed to let the male leave. If not successful, the former will often raise its abdomen, turn around, and eventually crawl away, dropping down into nearby vegetation, or simply fly away.
  • The Silvery Checkerspots are believed to have extirpated in the US state of Connecticut, where they have been enlisted as a ‘species of special concern’.
