Insect eggs: Leptoglossus balteatus
What you see in the first photo are not caramels, but eggs, yes, square eggs, belonging to the bug in the second photo, scientifically named Leptoglossus balteatus (Hemiptera - Coreidae).
Leptoglossus balteatus is a species known only from the Greater Antillas, The Bahamas, St. Thomas, and Florida. These bugs are considered an agricultural pest because they feed on several crops including tomatoes, guava, oranges and cowpeas. In the literature there is not much information on their stages of development, but certainly the morphology of eggs is amazing.
