It's the final match up of our first round in the Great Ontario Bug-off!!
It's Blattodea (cockroaches) versus Trichoptera (caddisflies). Vote in the comments!

(ps. if you don't vote Blattodea- Ernie will hear about it)

Diversity of Rhyacophila (Trichoptera, Rhyacophilidae) in the Hengduan Mountains Aquatic insects are particularly dependent on environmental conditions because their life cycles are directly linked to physico-chemical conditions in freshwater habitats. Here, we combine DNA barcodi...

Aquatic insects and environmental conditions are inextricably linked - this new study from China's Hengduan Mountains explores the diversity of the unknown fauna of Rhyacophila (Trichoptera, Rhyacophilidae). ➡ Learn more here: doi.org/10.3897/zook...

A new species of Oecetis McLachlan, 1877 (Trichoptera, Leptoceridae) and new distributional records of Trichoptera in the eastern Amazon The Amazon is one of the most diverse biomes on Earth, and most of its area is in the territory of Brazil. Even though it harbors most of Earth’s diversity, species remain to be described. Therefore, ...

A recent study describes a caddisfly species, Oecetis amplicauda, from the Amazon - one of Earth’s biodiversity hotspots - and expands the known distributions of eight additional caddisfly species. See how they've done it here: doi.org/10.3897/zook...

Relationship of Trichoptera species in Iceland with Europe and North America In the present study we examine the geographic variation in the COI mtDNA barcode marker in eight Trichoptera species from Iceland to determine their postglacial colonisation history. The patterns in ...

Unraveling how Iceland’s #caddisflies colonised the island after the last Ice Age, this study uses COI mtDNA barcodes to trace multiple waves of arrival and unique Iceland-only lineages. The results reveal... doi.org/10.3897/zook...

3/4 We assessed if #eDNA can capture the temporal changes of #Ephemeroptera, #Plecoptera, #Trichoptera, and #Diptera.

We found pronounced, cyclic phenological trends in most groups: the communities diverged from spring to summer and then in fall gradually returned closer to the spring state.

Proceedings of the 18th International Symposium on Trichoptera Since 1974 caddisfly researchers have met every three years to share developments on all aspects of Trichoptera research from faunistics, taxonomy, systematics, evolutionary biology, ecology and biomo...

Diversity, abundance and distribution of caddisfly (Insecta, Trichoptera) families in relation to environmental parameters across freshwater streams in Singapore In land-scarce Singapore, where fresh water is a critical resource, Trichoptera communities can serve as a biomonitoring tool, yet are poorly known. This study seeks to address this gap by establishin...

Happy 3. #HexapoDezember. Heute ganz klar #Trichoptera. Fliegen wir auf die Köcherfliegen 🤗📸⬇️

Dieses Bild zeigt eine Köcherfliege (Limnephilus lunatus), die auf einem verwitterten Stück Holz vor schwarzem Hintergrund sitzt. Das Insekt weist eine charakteristische orangebraune Färbung mit auffälligen weißen Markierungen auf den zeltartig gefalteten Flügeln auf. Die langen, fadenförmigen Antennen ragen deutlich nach vorne, und die zarten, segmentierten Beine sind klar erkennbar. Der behaarte Körper und die Flügel der Köcherfliege fangen das Licht ein und heben die feine Flügeladerung hervor, die typisch für diese aquatische Insektenart aus der Familie der Limnephilidae ist.

Die Larven der Mond-Köcherjungfer
(Limnephilus lunatus) entwickeln sich im Wasser. Wie bei vielen aquatischen Insektenarten währt das Larvenstadium deutlich länger als das Leben als adultes Insekt.

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.

Draufsicht auf eine Köcherfliege der Gattung Philopotamus, die auf rauer, grau-weißer Gesteinsoberfläche sitzt. Die Flügel sind dachförmig über dem Körper zusammengelegt und zeigen ein auffälliges Muster aus goldgelben und dunkelbraunen Flecken und Bändern. Zwei sehr lange, fein segmentierte Fühler erstrecken sich nach vorne, die etwa doppelt so lang wie der Körper sind. Die Flügel weisen eine leicht bräunliche Grundfärbung mit deutlichen dunklen Punkten und Flecken auf.

Seitenansicht einer Philopotamus-Köcherfliege auf verwittertem Steinuntergrund. Das Insekt präsentiert seinen charakteristischen Körperbau mit behaarter Kopfpartie, deutlich erkennbaren großen, dunklen Facettenaugen und goldbraun behaarten Körpersegmenten. Die langen Fühler zeigen feine Segmentierung mit abwechselnd hellen und dunklen Bändern. Die zusammengelegten Flügel offenbaren das typische Muster mit gelben Grundtönen und dunkelbraunen bis schwarzen Flecken und Bändern. Mehrere lange, schlanke Beine sind sichtbar, die vom Körper abstehen.

Detaillierte Seitenansicht einer Philopotamus-Köcherfliege auf steinigem Untergrund mit Flechten. Besonders gut erkennbar sind die dichten, goldbraunen bis orangefarbenen Haare am Kopf und Thorax des Insekts. Das große, dunkelbraune Facettenauge ist deutlich sichtbar. Die Fühler weisen eine präzise Segmentierung auf. Die Flügel zeigen ein komplexes Muster mit goldgelben Bereichen, die von dunkelbraunen bis schwarzen Querbändern und Flecken durchzogen sind. Die langen Beine mit ihrer charakteristischen Färbung sind gut zu erkennen, ebenso die feine Behaarung des gesamten Körpers.

Die Larven der Köcherfliegen, hier Philopotamus sp., entwickeln sich in Gewässern. Der wiss. Name der Köcherfliegen "Trichoptera" bedeutet Trichos = Haar und Pteron = Flügel. Warum, ist hier gut zu erkennen.

Four more #caddis species in the garden in the last few nights: Tinodes waeneri, Molanna angustata, Mystacides longicornis and Oecetis ochracea (probably). #TeamMoth #MothTrapBycatch #Trichoptera

Now up to four #caddis species for the VC 61 (East Yorkshire) garden, the latest being a rather smart Glyphotaelius pellucidus. #TeamMoth #MothTrapBycatch #Trichoptera

I thought I'd have a go at IDing #caddis as moths aren't challenging enough : / I think the first three species are Limnephilus marmoratus, L. auricula and Stenophylax permistus (gen. det.), but am happy to be corrected. Maybe also L. auricula for the last? #teammoth #Trichoptera
