Box Bug

A slender, reddish-brown coreid bug historically restricted to box trees in southern England but now expanding its range northward. It feeds on developing fruits and seeds of box and hawthorn.

💡

Did You Know?

Once Britain's rarest shieldbug confined to a single box woodland, it has expanded dramatically northward since 2000 due to warming temperatures.

Water Measurer

A very slender, elongate semi-aquatic bug that walks slowly on water surfaces in the Americas. Its head is exceptionally long and narrow with a small rostrum at the tip. It moves with slow, deliberate steps along pond margins.

💡

Did You Know?

It is so lightweight that it can walk on the water surface without breaking the surface tension, leaving no visible dimples where its feet contact the water.
