Adults can be anywhere between 1/6 and 1 inch long . Larvae are small , legless , slug - like maggot that are often found crawling around colonies of pest insect .
grown syrphid flies eat pollen and nectar , while the larvae are officious chowing down on various soft - corporal worm , including aphids , thrips , leafhopper , ordered series and caterpillars . Each maggot can eat up several hundred insects during its larval microscope stage .
Because grownup syrphid flies deplete pollen and ambrosia , it ’s important to provide them with as many flowering plants as possible , from other season until first frost . They are particularly fond of extremity of the aster mob ( Asteraceae ) and the cultivated carrot family ( Apiaceae).Having a diversity of bloom plant life in and around fields and gardens supports a great number of these very beneficial worm .

Ladybugs do not have specialized mouthparts for access nectar from deep , tubular flowers , like bees or butterfly do . Because of this , they necessitate to source ambrosia from shallow , expose flowers . Members of the Apiaceae class are ideal campaigner , including dill , Florence fennel , angelica , Petroselinum crispum , cilantro and hazardous parsnip .
5. Parasitic Wasps (40 different families, with thousands of species)
With a terrible diversity of physical appearances , parasitical wasps are a complex group of insects . They can be as lowly as a gnat or as long as a darning needle . In general , most are not capable of prick humans , and all use other insects as host for their developing immature . Adult wasps stick in orchis into host insect and the resulting larvae pass their entire life within the host worm .
While grownup WASP are sole consumers of pollen and ambrosia , they use century of unlike worm as host for their developing untested , including aphid , beetles , fly , shell , truthful bugs and caterpillar of every form .
