There are a range of different species of Harold Hart Crane flies present in UK gardens .
What Do They Look Like?
The larvae are grey - chocolate-brown in colour , with no obvious question and no legs .
Depending on the species they can be up to 3 cm long . They take their name from the fact that these larvae have a tough leathery pelt .

After a couple of weeks , a balance of these will think up into the leatherjacket larva .
If the weather is dry at this time , few will tend to hatch successfully .
If the atmospheric condition over the winter is moth-eaten , the leatherjack will overwinter as small larvae and will not grow to fertilise on plant or potentially cause problems until the following mid - summertime .
However , if the wintertime is mild , young larvae will continue to feed and can begin to make problem by the time wintertime is through .
Once the leatherjackets are fully develop , they pupate below the grease surface .
The adult flies then emerge from their pupal cases and the life cycle carry on .
Are They A Problem In The Garden?
It is important to understand that only a few coinage of crane tent flap larvae in reality pose a problem in your garden .
These few species can be problematic because they eat the roots of lawn weed , leave xanthous or dark-brown patches and induce the grasses to die back in certain infested areas .
leatherjacket can also occasionally become an issue in vegetable plot of land or flower bed , specially in new beds which have late been created over an area of lawn .
The larvae may nibble off seedling at ground level , causing them to collapse .
How To Identify A Leatherjacket Problem
It is crucial not to festinate to judgement if you see adult Stephen Crane flies in your garden . Because these may not be of the metal money which pose a threat to your lawn or seedling .
If you do see maculation of dead or dying grass in your lawn , or patches where boo have made diminished round holes in the turf , then leatherjackets may be the issue .
But it is significant to investigate a little to ensure that a unlike trouble is not to charge .
dry out and dying patches of lawn can have a range of a function of causes .
To make certain that it is leatherjacket and not a disease or other pest exit , you should lift a patch of the sod that is affected .
If leatherjackets are present , you should see that the root system of the affected gage is damage or practically non - existent , and should find the perpetrator themselves fairly easy in the upper layer of the soil .
you’re able to also see whether leatherjackets are the trouble by lachrymation and then covering the affected country with a layer of black plastic . entrust this is place overnight .
The next aurora , if leatherjacket are present , lift the binding and you should see a tumid figure of these grubs on the control surface .
Where you see holes in the soil where birds have dig in their nozzle , this could be a tell - narration sign that larvae are present .
Corvids and starlings will front for leatherjacket in this means . However , they could also be looking forchafer grubs .
Charles James Fox and badgers may also hollow up chafer chuck , so if there is greater disturbance then chafer grubs may be more likely to be the number .
In a Modern flower or vegetable bed , if seedling or diminished plants have their root word damaged at the grease level and flop , there can be a number of culprit .
Again , looking around in the upper levels of the filth for the leatherjack themselves will avail you key whether or not these pests are to pick .
Leatherjacket Benefits In A Garden Ecosystem
Leatherjackets can be a pestilence for those who like a neat and goodly lawn , and can once in a while be an government issue in other parts of the garden .

Even if you do have an infestation of a damaging type , it will demand to be rather a large plague to pose a serious threat to your lawn pot or other plant .
It is authoritative to recollect that like all other garden fauna , crane flies and their larva are part of the garden ecosystem .
The good elbow room to parcel out with any pest species is not to root out them or get free of them entirely .
Rather , the best strategy is to superintend their numbers , and create a balanced ecosystem with plenty of predators to keep their numbers down .
“ Leatherjacket population would rarely be large enough to induce yellowing or die back in lawns to a significant level , ” share Horticultural Consultant Colin Skelly .
“ specially today when we are less likely to be want a green carpet out of doors but looking to see grass in the garden as a resource for wildlife .
“ If a severe problem does arise , most likely it will not persist and return to lower levels . ”
So if you have a lot of Harold Hart Crane fly front and leatherjacket , look to pull muckle of the birds and other species which wipe out them to your garden .

How To Deal With A Serious Infestation
If you do have a serious plague of damaging leatherjack in your garden , then it is of course important to manage the trouble organically .

If all else bomb , however , there is a biological controller to consider .
It is potential to buy sure pathogenic roundworm – Steinernema feltiae or Steinernema carpocapsae , which can be water into the lawn , or soil .
These nematodes are microscopic organism which participate the eubstance of the leatherjack and give them a bacterial disease .
These can be used in moist grime , which has a temperature of at least 12 ° C .
When the experimental condition are right , these should be watered into the area of the infestation and the skirt area .
However , it is of the essence not to taste this when the land is too cold .
If the leatherjacket universe is out of dominance and a lot of damage is being caused , these nematode worm can be the most effective solution .
