Spring Insect Bundle

hi all! i'm trying to finish the Spring Insect Bundle in the museum before the season ends, and i'm missing whatever the bug on the far left is. i think it's a Luna Moth? can anybody confirm the bug, and if you caught it, where/when did you find it? i've been constantly reloading a nighttime save trying to find one but no luck so far lol!

EDIT: over 130 days since i made this post, but i caught the Luna Moth in my second Spring! i was literally on my way to make a save and reset for it on my farm and it just showed up in front of Hayden's house on the way lol. i stopped playing for a while to wait for the first big update, so i don't know if they adjusted the spawn rates for that, but good news- it exists!!!
