Back in June my parents decided to take an impromptu vacation to Cabo San Lucas, Mexico–every college kid’s dream, right? Well, it wasn’t impromptu (it was for their wedding anniversary) and “the kids” were never invited to begin with. Still, that’s not how I like to tell the story at family gatherings when I attempt to paint my parents as neglectful. (They’re not, though some extra spending money wouldn’t hurt!) But when I was reading through Arthur V. Evans’ book Beetles of Eastern North America, I came across a section titled “Parental Care,” and realized, trip to Cabo or not, I have it significantly better than beetles do when it comes to parent-child relationships.
As Evans explains, “For most species of beetles, care of offspring is limited to selection of the egg-laying site,” but there are some species that go beyond the call of duty. “Some ground beetles (Carabidae) deposit the eggs in carefully constructed cells of mud, twigs, and leaves,” while “some water scavenger (Hydrophilidae) and minute moss beetles (Hydraenidae) enclose their eggs singly or in batches within cocoons made of silk secreted by special glands in the female’s reproductive system.” (Evans 20)
But it’s the Nicrophorus beetles who win the #1 Parents Award . “They meticulously prepare corpses as food for their young by removing feathers and fur, reshape them by removing or manipulating legs and wings, all while coating the carcass in saliva laced with antimicrobials that slow decomposition.” (Evans 21) A beetle’s version of a home cooked meal!
