Here are some building instructions for making creepy and crawly spiders out of LEGO® bricks! While spiders are far from my favorite creatures, the boys love them. These spiders were created by Aidan (age 13) and Owen (age 7) with a few adjustments by me.

In the instructions, I have used brick names as used on Brick Link to make it easier in case you want to order individual LEGO® bricks to supplement what you have. Who really knows what bricks are called? I didn’t, until I started writing these instructions! I have a separate post on how to use Brick Link. It’s a great site for ordering any LEGO® piece including minifigures, accessories, extra wheels, etc, etc.

We used hinge plates (Brick Link name) for the legs because they can be posed and then lock in place. The front legs of each spider have ball and socket joints also to make them more posable.

Black Spider

Step 1: Line up the pieces shown. This is two black 1 x 4 curved slopes (inverted), two 1 x 2 black plates with angled handles, and two dark gray 1 x 2 plates with a ball on the side.

Step 2: Attach the two curved slopes to the plates with the angled handles. Then add a 2 x 4 black plate (flat brick).

Step 3: Add a 2 x 3 black plate and a 2 x 2 black plate.

Step 4: Add a 2 x 2 black plate and two 1 x 2 black plates to the back of the spider’s body.

Step 5: Add a 2 x 4 curved slope and a 1 x 2 slope (30 degree). Then add two 1 x 2 black tiles (the smooth pieces) and two 1 x 1 red round plates to the front of the spider.

Step 6: Add teeth (1 x 1 white plates, modified with one tooth). Then build the legs. The pieces on the left will build one front leg and the pieces on the right will build one of the back legs. There are two front legs and 6 back legs.

Step 7: This shows the completed front leg design (left) and the back leg design (right).

Step 8: Snap on all the legs, and your spider is ready to do creepy, crawly spidery things!

Brown Spider

The brown spider can also be found in our upcoming book – Epic LEGO Adventures with Bricks You Already Have. This book is filled with five funny adventure stories and instructions to build all of the projects in the stories. The spider is part of a chapter about a bug science lab and some crazy mutant bugs that grow to enormous sizes! 🙂

Step 1: Start with a 2 x 4 brown plate.

Step 2: Add a 2 x 4 brown plate, two 1 x 2 black plates with angled handles, and two 1 x 2 plates with a ball on the side.

Step 3: Add a 2 x 6 black plate and a 2 x 3 black plate.

Step 4: Add a 2 x 4 black plate, and then a 1 x 2 black plate. Attach two 1 x 2 brown curved slopes on top of the 1 x 2 black plate.

Step 5: Attach the two 4 x 2 wedge bricks and then add a 2 x 4 brown plate behind those.

Step 6: Add the four 1 x 2 brown slopes. (Or use 2 x 2 slopes.) Add the eyes and teeth.

Step 7: Turn the body over. Add the two 1 x 2 brown plates just behind the black pieces, one on each side. Then add the 1 x 3 brown plates, one on each side.

Step 8: Build the two front legs. Each one has two 1 x 2 brown plates, a 1 x 2 light gray plate with a socket on the end, and a 1 x 2 dark gray plate with a ball on one end and a socket on the other end.

Step 9: Build the 6 back legs. Each back leg has a 1 x 2 brown plate, a 1 x 2 black plate with a clip on the end, a 1 x 2 black hinge plate with one finger, and a 1 x 2 brown hinge plate with two fingers.

Step 10: Attach all the legs, and the spider is complete!

Long Legs Spider

This spider has the same basic body structure, except that we used three segments for each leg instead of two. I think this one is my favorite! Well, if I *had* a favorite spider, that is…

Have fun building!
