Many of us regard bugs and insects simply as pests -- to be rid of. Our guests today know that, and hope to change the hearts and minds of the insect-averse. Spider glue researcher Sarah Stellwagen waxes poetic about the mysteries and science of spider webs. And entomologist Mike Raupp, also known as ‘The Bug Guy,’ is on a mission to help people understand our connection to the creepy crawly critters, starting with the fascinating life cycle of what he claims as his ‘spirit bug’ -- the stupendous cicada. We preview their upcoming talks at the Natural History Society of Maryland.
