trying to identify this strange bug
My 6 yr old discovered this “pupa” while on vacation at her grandmother’s in the BC interior. She was on a creek at the time. Here is a photo.

Hi Monique,
This is a Caddisfly Larva. Adult Caddisflies resemble moths. The larvae are aquatic and are called Caddisworms. Many species construct portable cases around their bodies which later become pupal shelters. Sticks, small pebbles and other materials can form the basis of the case. Each species has a distinct type of case with specific building materials.

Hi Rebecca,
This is a species of Caddisfly, Order Trichoptera. They resemble moths and are poor fliers. Larvae are aquatic and the larvae build homes by cementing sticks and stones together, forming a tube which is used as protection as well as camoflauge. There are over 1000 species in North America. Sorry I can’t give you an exact species.

playground bugs [part 2]
Thank you for writing back to us! WE LOVE YOUR SITE!!!!!
We are sending two medium sized photos of our Caddisfly [we thought the other photo we sent might be too small to be seen on the site]. We hope they help others! We also included our favorite stag beetle photo and praying mantis photo [it stayed on the wall next to our classroom door for days! We think it was listening in!] Thank you again for your help!
Always looking for bugs, Fours and fives in PA

Dear Fours and Fives in PA,
Thank you for the additonal photos. We are posting them immediately.

What are these playground bugs?
We are so happy to have found your web site! We are a class of 4 and 5 year olds in PA. We take photos of bugs everyday but then we have no clue what they are. We used the photos on your site to identify some of the bugs we have photographed. Like the Wheel Bug that visited us last week. The second photo is of a bug we have not named yet so hopefully we can start off calling it the proper name. We like its funny "nose". Obviously we REALLY need a bug encyclopedia! THANK YOU VERY VERY MUCH!

Dear four and five year olds,
I’m so happy to see you are budding entomologists. Your other insect is a Caddisfly. They are members of the order Trichoptera that begin life as aquatic larvae. The larvae construct homes from sticks and tiny pebbles which are cemented togethe, acting as both protection and camouflage. The larvae are sometimes called Caseworms.
