Beautiful display, but a bit fragile

LC May 18, 2026

This LEGO insect set looks absolutely amazing on display, and the details are incredible. However, a few parts are not very stable and tend to fall apart easily if you move them. Great for a shelf, just be careful handling it!

OBSESSED!!

Ashley November 30, 2025

I've been eyeing this set for the longest, so when it was half off for black Friday I snagged it! It's such a cute set if you're an entomology girly like me. It was fun to put together and I love the way they turned out. I wouldn't say it's a difficult build, but I would not recommend it for younger children, they may struggle with the instructions as it's a bit more intricate.

Not Weird At All

Ed December 31, 2025

These are beautiful and I ain’t seen anything like this in a Lego! Not ever. Like I used to use Legos to make block houses and then there were fire truck sets but I never liked the little men with the faces painted on them. Just didn’t like them. Then in the 80s my buddy Bravo got the Millennium Falcon from Star Wars and that was amazing and yep I broke it when I knocked it over but he put it together again and then got a case for it so I couldn’t break it again. And now these snap-together insect Legos are like the Millennium Falcon all over again in terms of amazingness only not so vulnerable to getting knocked over and pieces going everywhere. If the wings or the legs could move it might be better but that’s just being picky. I like these here and they ain’t just for kids. They say for adults but they’re okay for kids, there’s nothin inappropriate going on or anything, just plain Lego fun with a hint of science. Good for grandkids.

JUST BUY IT!

Rusty February 4, 2026

If you’re new or old to Lego this build is fun in many ways. Each index is about 8-10 inches yall. And they are very colorful, So get a shelf ready.

Lego and Bug lovers combined

Cassandra June 11, 2026

This is a fantastic Lego set, it is fairly easy to assemble, some of the parts on the Insects are movable and it creates a nice view on the shelf. Kids can do this too if they are Lego lovers my son who is under 10 can build adult sets.

Beautiful but fragile set.

Marie March 7, 2026

Lego Ideas sets are geared more toward adults, I believe. They are intricate and beautiful display sets. The Insect collection offers 3 separate insects to build. The builds are challenging and time consuming, but turn out amazing. The butterfly is colorful and sturdy, and the preying mantis seems delicate and yet, is very hardy. The only build I had an real issue with was the beetle. The wings, fabulously rendered here, are very touchy and will fall off with even a little touch, which makes displaying the beetle with opened wings is difficult, but possible.

Great for a group!

Mokacincy28 December 21, 2025

I bought these and built them with friends. Really fun to build side by side. Beautiful end result and fun build. Most of the time you are building the branches the insects sit on and not the actual insect so thats not as fun. Also the price may be a little high for what you get. However over all I'm extremely satisfied and hope Lego makes more builds like this! Note that the beetle and mantis can stand on their own legs or on the branch, while the butterfly can only be mounted on the branch. Ps. You get cute little ladybugs and a bee!

Not in new condition as advertised.

Palmer April 6, 2026

This was from a secondary seller through Walmart. Advertised as new. But box was in bad shape and had been opened. It appeared all the bags and instructions were intact, so I kept it. But I could not give it as a gift because of the condition.
