The greenhouse rove beetle is widely known for the benefits it can provide greenhouse growers. They are a soil-dwelling beetle with aggressive feeding behaviour. They were first discovered as a useful form of biocontrol when researchers stumbled upon one feasting on their laboratory population of fungus gnats. Now available to purchase worldwide, both larvae and adults will readily hunt the eggs, larvae and adults of fungus gnats and western flower thrips.
Rove beetles perform many ecosystem services. Some species are excellent predators, contributing to pest control. Whereas others are detrivores, feeding solely on rotting vegetation.
These beetles are used as a form of biocontrol to keep fungus gnats at bay in greenhouses.
These beetles are fairly small (5mm). They are brown and glossy, possessing reduced elytra (wingcases). Adults are winged and can fly, however, these beetles spend most their time hunting and growing in the soil media. Larvae begin white but slowly turn yellow-brown.
These beetles can perform an array of services that can benefit the wider ecosystem, including pest control and assisting decomposition of organic matter.
It's not suggested to treat gardens for these insects.
