Okay, this is something I haven't seen before. I've seen the Banana Slug against the buildings (very rare) and on the north bank of the middle river (rare) and once in the grass just south of the General Store, heading for the buildings. They do move until they reach a barrier, and that barrier is usually the buildings or the north bank of the river.

But this time I saw one moving north through the Botanical Garden. Fumble fingers that I am, I couldn't snap the screen shot until the slug was right up against the fence. They move pretty fast for slugs. I snagged him (150 coins!) rather than wait to see if he could get through the fence.

Has anyone got any tips on catching dragonflies? Have caught a couple with immense amounts of patience! Just wondered if anyone has an easy method?

You can walk out on the docks.

I've just started this game and don't know how to catch a butterfly. Maybe it's a monarch. It flies around the courtyard area to the right (my right) and in front of the Town Hall. It never "lands" just flies around and around so I find that my mayor slaps the net down to no avail. Do I need a gold net? I've only got a silver one at present.

Is it flying round a lamppost in the evening? Aim at the foot of the post - that usually works after a couple of tries.

Ah. Night. Lamppost. Gotcha!
Thank you, Arnie.

Aim for the shadow of flying bugs. The larger the net the easier they are to catch.

Hmm. Never considered aiming for the shadows. Thank you for your suggestion. I did catch a butterfly by aiming for the lamppost, so I'll add shadow watching to my repertoire, lol.

So the banana slug is quite small? I couldn't see it in the screenshot? It appears skinnier than the revolting slugs that I have to clean up?

The Banana Slug is small but not as small as an Earwig. It is yellow. In my screenshot it is unfortunately raining and it looks like a streaking raindrop. Look along the upper fence line, inside the Botanical Garden, to the right of the fence opening, above the third Blueflower Lemongrass plant. Hope that helps.
