African Citrus Psyllid
A small brownish psyllid that causes distinctive pit galls on citrus leaves. It vectors the African form of citrus greening disease and is expanding its range into Europe.
Did You Know?
Unlike the Asian citrus psyllid, this species prefers cooler climates and has been detected in Portugal and Spain, threatening Mediterranean citrus production.
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.
