Your letter to the bugman:  I took this photo June 24,2019, there is a interpretative centre where I took the pic with research material and I looked online and cannot identify it, The closest I found was a Festive Tiger Beetle but no where close enough. I spoke to an entomologist still no luck.   Any assistance will be appreciated. Thank you

Nuttall’s Blister Beetle

Dear Steve,
Your images are positively gorgeous, and they beautifully represent this Nuttall’s Blister Beetle,
Lytta nuttalli, which is pictured on BugGuide.  According to BugGuide:  “Adults feed on legumes” and the flower in your image does look to us like a legume.  Blister Beetles in the family Meloidae should be handled with caution as many species can exude hemolymph containing the blistering compound cantharidin.  The infamous aphrodesiac Spanish Fly is produced by crushing the bodies of a Spanish Blister Beetle.

Thank you for the information. I have recently retired and bought a new camera and a macro lens and discovered  there really are a lot of interesting insects. I am enclosing a couple interesting photos, 1 a great picture of a Monarch butterfly, and the second which I didn’t notice the ladybug is chowing down the aphids on the plant. Thanks again for your assistance.
Steve
