Can anyone identify this little guy? Thanks in advance

Hi & welcome to the community ... Hard to be sure but possibly butterfly, best way to be certain is to bring it in, lay on kitchen paper in aerated pot, include a stick for it to climb up & see what emerges then set free when wings fully inflated & dry!

That's how I started off H with the butterfly house & five Painted Lady caterpillars with their own food ... they grew, pupated & eclosed ... fascinating!
The kit was supposed to be for children ... say no more! Lol
