Please note that the scale on the Y axis is not the same for the three graphs. Malaise Traps Malaise traps are designed to trap flying insects. Both groups were relatively abundant in the large field but very scarce in the small field. A comparison of syrphids collected each year in malaise traps reveal very similar profiles. Chrysomelids were only trapped in the large field.
Tabanid larvae are aquatic and often predaceous, some even feed on frogs.
As many have experienced, female Tabanidae feed on blood. Less well known is the fact that males feed on nectar and pollen. Halictidae were the most common group from the order Hymenoptera. Halictidae are solitary bees. Their larvae live in rotting logs and act as decomposers.
