Female wasp giving piggy-back ride to males! Sometimes they carry 2 males on their backs. Please look closely. You can count 6 antennae lower left, just under stack of 3 heads. And 3 abdomens are easy to count on the right. Similar triple-decker photos were in an earlier blog. These photos demonstrate that it isn’t such a rare occurrence.
Reminds me of a circus act! Please share with your buggy friends.
