This is the mayfly larvae Caenis luctuosa/macrura or more commonly known as small squaregill mayflies. The larvae are teeny tiny (2 -8 mm) meaning they are often overlooked. #aquaticecology #ecology #aquaticecologist #mayfly #taxonomy #science

This is the common alderfly, Sialis lutaria. It is one of three species found in the UK. The larvae live in mud and detritus under the water. They are aquatic predators with powerful jaws waiting for their prey under stones or in silt. #macroinvertebrate #aquaticecology #ecology

These have got to be my favorite Coleopterans. Larva is on the left and adult on the right. Such a cool transformation! #Coleoptera #Hapliplidae #Peltodytes StreamCLIMES

This little caddisfly cutie is Beraea pullata from the family Beraeidae. They have a curved case made from sand grains. They feed by gathering fine organic matter and shredding fallen leaves/plant material. #macroinvertebrate #caddifly #aquaticecology #ecology #caddisfly #rivers

What…wait. That’s not an invertebrate! 🥰. Wonder how much of my sample it ate!

Recreated this daft photo I took of my Dad almost 20 years ago. I miss how silly he was. #arran #grief

Its #PondWatch I'll start with this Berosus affinis Water Beetle - these beetles can rub the stridulatory patch on their wing cases their body to make chirping noises, used to both startled predators and communicate with other beetles, including during in courtship!

This is the caddisfly Halesus digitatus from the family Limnephilidae. This families cases are often made from a mish mash of plant and mineral materials, sometimes even shells (snazzy!). #caddisfly #caddis #caddisflies #aquaticecology #ecology #freshwaterecology #taxonomy
