Your letter to the bugman:  Hello, At first I thought these creatures were pieces of pond weed. However, on observing them for 10 minutes or so, I see they are ALIVE and they appear to be interacting with each other.  The are located in one small part of a garden pond. They appear to have a sucker on one end. I replaced the bug in the photo back in the pond! Thank you for any help in identification.

Caddisfly Larva

Dear Jo,
This is the larva of a Caddisfly, an aquatic naiad that will eventually metamorphose into a flying insect that somewhat resembles a moth.  Caddisfly larvae construct a shelter from twigs, shells, pebbles, and other debris, and different species of Caddisflies construct different types of cases.  This image on Ed Brown Wildlife and Nature Photography looks exactly like your individual.  We are making your submission our Bug of the Month for April 2020.

Hello Daniel,
Thank you so much for this information – and so quickly!  I’m sure our caddis flies will be honoured to feature as your Bug of the Month!
Your site is wonderful. I’m just about to buy the Kindle version of your book, which I must get through Amazon UK, as US Amazon will not accept an order from my UK account.
Here’s wishing you and all concerned at What’s That Bug? the best of health in these difficult times.  And many thanks again for the information.
Kind regards,
Jo

  1. We found these larvae in a shallow pond in Vermont, thank you so much for identifying them here! They are swimming around among tadpoles and we had no idea what they were. They look a little like swimming pinecones.
