Pumpkin seed shaped water bug resting on vegetation above the surface of the water..
I saw at least 8 of these giant water bugs up out of the water yesterday. This is probably Belostoma flumineum, not the most giant of the giant water bugs. Neat to see this behavior even though I have no idea what they're up to. #aquaticInsects #macro
An analytical synopsis reports 1,510 caddisfly species, representing 28 families and 155 genera, from the 63 states and provinces of Canada and the USA, based on records spanning 270 years.

Freshwater habitats are crucial - and aquatic insects are key indicators of ecosystem health. 🐛💧
At the #AquaticInsects SIG, we’ll explore conservation, adaptive management and how data shapes freshwater biodiversity science.

An #OpenAccess study found that temperatures & lower oxygen levels in water are causing #AquaticInsects to become smaller & experience increased mortality, with potential disruptions to aquatic ecosystems.

Figure 1 in van Leeuwen et al. (2025): "Map of the world with bar charts per continent that indicate the total number of families in each insect order. The colouring of the bars indicates the number of families in each order, with unavailable (orange) and available (blue) length–dry mass power regression parameter information (see Figure S1 for a similar figure at the genus level). The Megaloptera category includes the Neuroptera families."

Day 3: Diving Beetle
🪲The predacious diving beetle larvae are known as "water tigers" because of their appetite. They have strong jaws and inject enzymes into prey, then suck up their remains. Brutal.
