              Why do Moths Matter?

       It seems that beautiful butterflies get all the attention, with pollinator gardens
       and pathways. It is important to protect and aid the butterflies, but we need to
       also understand and appreciate moths and how they benefit us. There are also
       gorgeous and unique moths, but most are nocturnal, so we do not see them as
       often. Let’s take a closer look at moths and learn why they matter.
       Differences between moths and butterflies: Both butterflies and moths belong to
       the order Lepidoptera, but there are physical and behavioral differences be-
       tween these two insects.
         ven though we are much more familiar with butterflies because they are
      Eactive in the daytime, moths in Connecticut significantly outnumber
       them. There are 435 moths identified on the CTButterflyIdentification.org
       website while approximately 120 butterflies occur in Connecticut. Within the
       U.S., moths outnumber butterflies 10 to 1.
