The presence of dragonflies in or nigh fish - free ponds can have a negative impression on pollinators and , consequently , on plant pollination . As a gardening and landscape gardening expert , I have observed this phenomenon firsthand and have see the wallop it can have on the ecosystem .
Dragonfly larvae , also known as nymphs , are aquatic tool that spend a pregnant serving of their life round in water . They are voracious marauder and feed on a multifariousness of aquatic organisms , including small louse and even pollywog . In fish - destitute pool , where there are no Pisces to prey on dragonfly larvae , their universe can thrive .
When these dragonfly larvae eventually transform into grownup snake feeder , they continue to feed on insects , include pollinators such as bees , butterflies , and other flying dirt ball . They are agile hunters , capable of catching their target in mid - melody . This is where the disconfirming burden on pollinator hail into free rein .
As dragonflies become more abundant in and around the fish - gratis ponds , their depredation on pollinator increases . They actively seek out these insects as a food for thought informant , leading to a meaning reduction in their population . This declination in pollinator numbers can have a direct impact on industrial plant pollination , as these dirt ball play a crucial role in shift pollen between flower .
In my own garden , I have noticed a decrease in the number of pollinators visiting my prime when sewing needle are present in nearby pond . This has resulted in a concentrate yield set and overall production of my insect - pollenate plants . It is disheartening to witness the diminution in pollinator natural process and the subsequent effect on my garden ’s productivity .
The electronegative consequence of dragonflies on pollinators can be particularly pronounced in areas where there are limited substitute author of food for these predatory insects . In such cases , they may heavy swear on pollinator , leading to a more substantial impact on works pollination .
To sum up the negative effect of dragonflies on pollinators:1 . mosquito hawk feed on pollinator , reducing their universe and potentially causing a declivity in their numbers.2 . This reduction in pollinator copiousness can directly affect plant pollination , leading to decreased fruit set and productivity in insect - pollinated plants.3 . In field with special alternative food reservoir , dragonflies may intemperately bank on pollinator , exacerbating the damaging shock on plant pollination .
It is significant to consider the symmetry of the ecosystem when designing garden or landscape . While dragonflies are beneficial in controlling sure louse population , their presence near fish - free pool should be carefully managed to minimise the damaging effects on pollinators and plant pollenation .
