Spotted Lanternfly ( SLF ) is an encroaching insect coinage native to parts of Asia , including China , Vietnam , and Bangladesh . First spotted in the U.S. in Pennsylvania in 2014 , efforts to curb this insect pest have been aggressive , but it has spread throughout the state and has now been seen in surrounding states .
The dependable news is that Spotted Lanternfly does not bite citizenry . The high-risk news is , lanternfly decimate many food crops and landscape plants , including grapes , peach , rosebush , blueberries , apples , maple , birch , cherry , sycamore , willow tree , staghorn sumach , cuke , St. Basil , daylily , and others ( at last report card , there were 65 known species of plants ) . Spotted Lanternfly does not fee on the fruit of food for thought crops – they run on the woody parts of the tree and plant , which affects the long - terminus health of the flora . SLF is most likely to be found in their host plant life : tree diagram Of Heaven ( Ailanthus altissima ) , also an invading mintage , smuggled walnut tree , and hops .
How does Spotted Lanternfly kill plants?
Spotted Lanternfly has pierce , sucking mouthparts and is a bigplanthopper . This pest practice its mouthparts sort of like a straw – they insert it into the sap conducting vessel ( the bast ) of a plant and feed on the sap . When the SLF is untested , the mouthpart are tippy and they tend to feed on the undersurface of leaves and the leafstalk of leaf – the tender parts of a plant . As they mature , the mouthpart become firm , and the insects can pierce throughold barque on treesand provender on the sap .
Like many other insects , SLF leaves “ honeydew ” in its wake – sap from the tree that is relatively undigested , which has passed through their body . There are circle of lettuce continue in the honeydew melon , which attract fungus kingdom , put further stress on the Sir Herbert Beerbohm Tree . Honeydew appear as a awkward , black , sooty mould with a sour smell and may settle on the fruit , which bankrupt it .
To make matter worse , edged insects expand on honeydew – it ’s not unusual to see a yellow crownwork literally following an grownup Lanternfly and sucking up the honeydew as it emerges from the Spotted Lanternfly ’s trunk .
SLF is not get laid to do any morphological damage to homes . Even though they may pull together en masse shot on a paries , they wo n’t attempt to get inside the paries outer space and overwinter asother insectsdo . The adult will croak during the winter from cold temperature .
What are the natural enemies of Spotted Lanternfly?
presently , the only know rude enemies of SLF are Praying Mantids , spider , andwheel bug ( an assassin hemipteran )
Which organic insecticides kill Spotted Lanternfly?
Researchers are still experimenting with insecticides to combat Spotted Lanternfly . As of this metre , these 4 insecticide approved for constitutive grow show an gist on SLF . Note that they will address insects present on the plant at the sentence of lotion but will not kill visitors after lotion ( they are not systemic ) . The 4 organic insecticides are :

The life cycle of Spotted Lanternfly
distaff SLFs lie eggs in September in bollock masses . Each female person can lay up to 2 ball masses with each mass between 30 - 50 eggs . The female lays her egg in rows and covers them with a secernment from her physical structure which is at first white but dries to a mud - like show . The covered testicle masses are comfortable to miss as they are laid in protect area where they will stay warm over wintertime . They ’re also easy to miss on Tree as they go in with Sir Herbert Beerbohm Tree bark or be misguided for actual clay . SLF egg masses can be found anywhere , admit physical object you would never suspect the insect would use . recognise Lanternfly is oftentimes moved this way – object with testicle people are moved to other geographies , their owners unaware of the insects .
SLF has only one generation per twelvemonth . Young Nymphs egress from the eggs in saltation and has 4 nymphal degree , each of which is cry aninstar(every time a houri drop its hide it ’s the next instar ) . In the first 3 instar stage , SLF are contraband with clean spots . In the 4th instar , they develop a red coloration ( see images below ) .
Spotted Lanternfly pop off directly from 4th instar to adult without the aid of a cocoon or pupa . The skin of the last instar cracks capable and the adult crawls out . At first , the adult is light-headed in color but darkens as it promptly dries . It can easily be identified by its black spots on its folded wings .
