Great shots Paul!
I tried it myself. I don't have a macro lens. So I used the 14-42mm kit lens with a 16mm extension tube. That costs some light and these bugs are almost constantly moving. Couldn't stop down further. So this one came out. Shot with E-M10 II @ 42mm, f 6.3, 1/60th, ISO 200:
Nicely done! Never tried extension tubes, but they did a great job. And yeah, this bugs are "annoying", especially if there is a lot of sun outside... they move like crazy. Your photo is great! Congrats.
While stuck at home the backyard is almost the only place to take pictures outdoors. Although it's not strictly forbidden to leave the house here in Hamburg. Here are some bugs enjoying the sun while its getting warmer.
