🔬 Today is #WorldTaxonomistAppreciationDay. Without #taxonomists, we wouldn’t know many #species or if they’ve vanished. Their work underpins #biodiversity and conservation. A rediscovery of the endangered #caddisfly Oecetis struckii in Saxony shows why accurate identification matters. 🪰

Limnephilus pati was first described by Irish entomologist Dr James O'Connor in 1980. Present in Ireland, it was believed to be extinct from our nearest neighbour. However, this is now the third site the species has been recorded from in Britain since 2020.

Nature’s little builders 🌿 In August, some of our monitors found as many as 1000 cased caddis in their sample!
Caddis larvae make protective cases from twigs, sand, and stones. Each one is unique!

Today we are celebrating ‘micro’ #caddisfly Monday with an inspiring entomological tale of unexpected discovery!
A rare caddisfly last recorded in Britain in 1945 has been rediscovered from the River Brathay by amateur Entomologist, Andrew Dixon.

Just spotted this little visitor on my kit on the River Thames – a caddisfly! With its long antennae and tented wings, it's a sign of healthy river life. Its larvae build underwater homes from sand and twigs. Nature's tiny architect! #RiverWildlife #Caddisfly #NatureNerd

A dorsal view of a small hoverfly 8-10mm long resting on a green leaf. The hoverfly - which is facing away from the camera - is long and tapering in shape; the abdomen broadens slightly at the midpoint before narrowing to a point. The hoverfly's large eyes, which are barely visible over its head, appear almost rust-brown on colour, while its thorax is a dull metallic bronze with three darker linear stripes running from the head towards the abdomen. A bright yellow, semi-circular marking is apparent between the base of the thorax and the abdomen, while the abdomen itself is marked by alternating black and yellow bands; the black bands have a very small, but noticeable "uptick" (similar to a curly bracket) into the yellow of the band above. The hoverfly's colourless wings are narrow and delicate in appearance; although transparent, they are crossed by thin, black veins, with very small black patches being apparent at the top edge of the wing approximately halfway along its length. Species tentatively identified as Sphaerophoria scripta.
A lateral view of a thick-legged hoverfly (Syritta pipiens). The small hoverfly, approximately 8mm in length, is resting on a golden yellow and white ox-eye daisy flower. The large, dark rust-brown compound eyes almost fill the hoverfly's near spherical head. The top of the thorax is black, while the sides are a pale, yellowish-grey in colour. The hoverfly's abdomen is long and narrow, before becoming more bulbous at the tip; it is generally black, with small patches of yellowish-grey markings on each section. The most distinctive feature of this hoverfly are its rear legs, which are significantly thicker near the body; it has the bulky-thighed appearance of a keen cyclist!
Caddisfly larva. The image shows a lateral view of a caddisfly larva measuring around 1.5cm in length. The top of the image shows a small, narrow and elongated dead leaf or similar small piece of foliage, which is dark brown in colour. The leaf is attached by a series of very fine, hair-like filaments to a structure beneath; this is long and tapering becoming progressively narrower to the right of the image, giving it a similar shape to a windsock, and is generally a greyish-brown colour, but speckled with grains of sands and grit. The grains are a range of colours: black; grey; red; white; and colourless/transparent. Some appear reflective, giving the structure a slightly sparkly, jeweled appearance. From an opening to the wider, left side of the structure protrudes the creature that constructed the masterpiece; a small, caddisfly larva is visible poking out from its protective case. Its head is small, rounded yet somewhat elongated, with large black eyes clearly apparent among the spotted white and brown markings. Long, straight antennae, which are banded brown and white, are pointing forward from the head. The caddisfly's legs, which also display brown and white bands, give the impression that it is wearing stripy stockings.
And not forgetting the #hoverflies; I've found a couple more species of them too! And another beastie lurking in the #pond - our first #caddisfly!

Here's a selection of Limnephilidae Northern Caddisfly larvae on the bed of this tributary of Stringside/Lode Dike #chalkstream. Most of these have used snippets of reed stem, with the ones lower right, mosaics of stones. #Riverflies #Trichoptera #caddisfly #chalkstreams #norfolk #invertefest 8/14

Following the recent paper by @aukeflorian.nl on #microplastic in #caddisfly cases, we revived an old blog post we published in the series "cabinet of freshwater curiosities" 15 years ago. Thanks to @robsaintjohn.bsky.social. freshwaterblog.net/2025/05/01/c...

Photo showing an aquatic insect larva, with the usual 3 pairs of legs attached to thoracic segments. The insect's body is of a beige color, with some darker areas. On abdominal segments, gills can be seen on the ventral side. At the tip of the abdomen, large hooks can be seen, which are used to grip onto the surfaces the larva lives on. Watermark identifying photographer as Geneviève Laurin.
#Caddisfly larva (Thichoptera) photographed against a synthetic surface. As for many insect larvae, these are aquatic. You can see abdominal gills on this specimen.

A mottled cream and brown caddisfly perched on top of a leaf, by the edge of a canal
King of the castle! Found my first caddisflies of 2025 today. Glyphotaelius pellucidus (I think, perhaps, maybe) - a species that lays jelly coated egg masses on leaves overhanging the water (affectionately referred to as "tree snot"!)

I love all the inhabitants of our pond - newts, tadpoles (frogs & toads), pond skaters, dragonfly & damselfly larvae, whirligig beetles, snails - but my absolute favourites are the #caddisfly larvae who live inside mobile homes made of leaves, plant stems, and other pond debris! #wildlifeponds 🌿

Cased caddisfly. I noticed a few of these in my pond when I was watching tadpoles. I took this one out temporarily to get a better look 🙂 #uknature #pondlife #caddisfly

Caddisfly moving their trailer house! They glue pebbles and other things to make a home. This one was scooting along in the springs.
