Scientific identify: Philanthus triangulum
What does it appear like? Superficially, the bee wolf resembles a standard wasp because it has the identical shade sample (black and yellow) and is roughly the identical dimension.
Where does it stay? The bee wolf is present in habitats with sparse, quick vegetation the place the soil is sufficiently sandy to enable digging. The local weather can also be a vital prerequisite as bee wolves want comparatively dry summers and happen largely in locations with lower than 700 mm rain per year. This insect is distributed from Spain within the west to Afghanistan within the east, and from Norway within the north to South Africa within the south. This is about the identical distribution as their prey, the (western) honeybee.
Many of the bees and wasps go to nice lengths to be certain their younger have the very best begin in life. The bee wolf is an ideal instance of this as the feminine goes to nice lengths to provision her nest with food for the following era. The grownup feminine feeds on nectar and pollen to present her with the power wanted for flight, however to present for her younger, she should stalk and seize unlucky honeybees.
Her prey is commonly distracted gathering nectar and pollen from flowers, and upon sighting appropriate quarry, she flies straight towards the honeybee and knocks it from its flower. On the way in which towards the bottom, the bee wolf stings the honeybee within the weak membrane becoming a member of the plates of its thorax, injecting a paralyzing venom.
While the honeybee is tangled within the vegetation or wrestling on the bottom, the venom acts shortly, and when the prey is safely immobilized, the bee wolf grabs it together with her center legs and takes off again to her nest. The nest of the bee wolf is a lavish aff air. The subterranean lair is dug in sandy soil by the feminine utilizing her entrance legs and mandibles. The tunnel might be as a lot as 1 m lengthy, a substantial distance for an animal that's not more than 16 mm in size. The first a part of the tunnel slopes downward at an angle of 30°, after which there's an extended horizontal part. Up to 34 lateral tunnels ending in a brood chamber are excavated horizontally on all sides of the principle tunnel. The feminine bee wolf shares every brood chamber with one to six paralyzed honeybees and a single egg that hatches right into a hungry larva.
The bees are smeared with a secretion from glands on the feminine’s head, and solely not too long ago has the rationale for this conduct been found. The nest of the bee wolf is heat and humid—an incredible place for the expansion of fungi and micro organism—and with out some technique of preservation, the larva of the bee wolf can be left with little greater than a mound of rotting bugs. The secretions of the bee wolf act like embalming fluid and clean all of the tiny nooks and crannies on the bee’s physique that off er an incredible place for the condensation of water. Without these minute condensation nuclei, droplets of water can't type on the bee and its physique stays dry—protected against the ravages of micro organism and fungi, which require moisture to survive.
Not solely this, however the feminine bee wolf additionally secretes a whitish substance from its antennae that incorporates symbiotic micro organism. These micro organism are taken up by the larvae and spun into the partitions of the cocoon when it's making ready to pupate. The micro organism shield the pupa from doubtlessly dangerous fungi, particularly in the course of the lengthy interval of hibernation. With the brood chamber absolutely stocked the feminine daubs the white micro organism paste from her antennae on the ceiling of the chamber. The chamber is then sealed. The white microorganism marker left by the feminine signifies the place her absolutely developed off spring ought to dig to escape from the brood chamber. This is essential, as the doorway of the chamber was crammed in by the feminine, as was the outer entrance. The absolutely developed wasp can't depend upon gentle to orientate itself, so the marker prevents it from losing time on the lookout for the nest exit within the incorrect place.
