I was concerned to find very few praying mantis egg sacs around my house this year. This morning, while walking my dog, I discovered one merely 10 cm above the ground surface. Further exploration in our small yard revealed 6 mantis egg sacs, all laid near the ground surface, which is why I couldn’t find them before. I wonder if this year’s prolonged hot summer, followed by rapid cooling, might have caused this 🤔#PrayingMantises #ClimateChange

Around this time a year ago I decided to finally get a guitar I’d wanted for a long time. The Hummingbird.

A study found red Euonymus flowers attract fungus gnats for pollination, while white ones draw bees, beetles & brachyceran flies. Dark-red color, short stamens, and acetoin smell might indicate a unique #PollinationSyndrome associated with fungus gnats.

A female clear-wing hawkmoth (Cephonodes hylas) is visiting the Gardenia tree in our yard to lay her eggs. I love watching their super energetic aerial show! The tree already has some larvae living in it as well. #biodiversity #hawkmoths #Sphingidae #garden

Found a dead Japanese jewel beetle (Chrysochroa fulgidissima) in the shrine near our house. It’s a huge one. Wondering how it feels to look so gorgeous even after death. Nature is amazing! #biodiversity #JewelBeetles #beetles #StructuralColor

Leaving the building after work, this guy caught my eyes. A beautiful green cicada, Hyalessa maculaticollis, symbolizing midsummer tradition in eastern Japan. Hey, I hope you're enjoying your ultra-short vacation to the fullest! #biodiversity #cicadas
