Halosalda lateralis is a Shore Bug (Saldidae) that mostly lives in the saline sandy environments along the maritime coastline, but occasionally also inland (rarely even non-saline). Several hours of inundation can be sustained while holding on to a submerged plant, by going into a stasis and thanks to special structures on the dorsum, under the hemelytra that provide a means of taking in some oxygen under water.

This specimen was around 4mm, see image here:

I've added some text in the species account that states "3,2-4,7mm"

Of course literature sizes will always vary a little. Cobben (1985) presents size ranges of 3,2-4,1mm for males and 3,6-4,6mm for females (my image shows a female), but also states that within this total range the animals from Europe's west coast are on average clearly larger than individuals from Britain and from the Black Sea area.
