To Bee or Not to Bee

A Short introduction to different types of bees, wasps and flies that are pretending to be bees or wasps.

Carpenter Bee

Tough Acting harmless bee, The common name “carpenter bee” derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo. Many species in this enormous family (genus) are difficult to tell apart. Most are all black, or primarily black with some yellow or white pubescence (the soft downy hair on insects and animals). Some differ only in subtle morphological features, such as details of the male genitalia. So, unless you have a microscope to look at bee penises then you can just call them a carpenter bee. (Below Eastern Carpenter & Violet Carpenter Bee).

Honey Bee

While about 20,000 species of bees exist, only eight species of honey bee are recognized, with a total of 43 subspecies.

Carniolan Worker – Apis Mellifera Carnica

Worker bees are the most familiar-looking member of the honeybee hive, as they make up about 99% of each colony’s population.

Worker bees are all female, and they do almost everything for the hive. From birth to her death 45 days later, the worker bee is given different tasks to do during different stages of her life. Worker bees are responsible for everything from feeding the larvae (the baby bees), to tending to the queen, to cleaning the hive, to collecting food, to guarding the colony, to building honeycomb.

Paper Wasp

Paper Wasp

Paper wasps are vespid wasps that gather fibers from dead wood and plant stems, which they mix with saliva, and use to construct nests made of gray or brown papery material. Some types of paper wasps are also sometimes called umbrella wasps, due to the distinctive design of their nests Will only sting if provoked but is extremely painful.

Bumblebee

Bumblebee

The sad fact is that i googled images for bumblebees and the first 100 or so images were of the transformers car “bumblebee” Moving on from that disgrace the bumblebee is so large it should not fly and a species of bee that most of us are able to identify from this fact. A bumblebee (or bumble bee, bumble-bee, or humble-bee is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. 

The word “bumblebee” is a compound of “bumble” + “bee”—”bumble” meaning to hum, buzz, drone, or move ineptly or flounderingly. The generic name Bombus, assigned by Pierre André Latreille in 1802, is derived from the Latin word for a buzzing or humming sound, borrowed from Ancient Greek βόμβος (bómbos).

Hover Fly

A true fly. The size of hoverflies varies depending on the species. Some are small, elongated, and slender, while others, are large, hairy, and yellow and black. As members of the Diptera, all hoverflies have a single functional pair of wings. Due to their colourings they are often mistaken for wasps or bees. Despite this, hoverflies are harmless to humans.

Hoverflies can be distinguished in the field by anatomical features such as:

  • The legs and mouthparts of hoverflies are usually not particularly long and thin.
  • Their facial cuticle often has prominent bulges and/or beak- to knob-like projections (most bee flies have an evenly curved or sloping face).
  • The wings are often clear or have smooth gradients of tinting.
  • Their abdomens and thoraces often have glossy cuticular body surfaces, abdominal colors are usually mainly due to cuticular pigments (bee flies are usually very hairy)

Yellow Jacket

Not much to say about these guys, we are all familiar with, perhaps too familiar with the common wasp. Interestingly the diet of the adult yellowjacket consists primarily of fruits, flower nectar, and tree sap. The larvae feed on proteins derived from insects, meats, and fish. Workers collect, chew, and condition such foods before feeding them to the larvae. Larvae, in return, secrete a sugary substance for workers to eat. As insect sources of food diminish in late summer, larvae produce less for workers to eat. Foraging workers will then pursue sources of sugar outside the nest including ripe fruits and human garbage.

Many of the insects collected for protein by the workers are considered pest species, making the yellow jacket beneficial to agriculture.

Mud Dauber

Mud dauber, “mud wasp” or “dirt dauber” is a name commonly applied to this family of wasps that build their nests from mud.

The organ pipe mud dauber builds nests in the shape of a cylindrical tube resembling an organ pipe. Common sites include vertical or horizontal faces of walls, cliffs, bridges, overhangs and shelter caves or other structures.

The nest of the black and yellow mud dauber is a simple, one-cell, cigar-shaped nest that is attached to crevices, cracks and corners. Each nest contains one egg. Usually several nests are clumped together and covered in mud. (below mud dauber & nest)

Giraffes & freshly cut grass…

That smell we love so much, that has even been bottled into a scent is the distress call of your freshly cut lawn. It is the release of a chemical defense and self administered first aid from the hundreds of thousands of injuries you just inflicted with your precious lawnmower.

Plants release a whole number of volatile organic compounds called GLV’s (Green leaf volatiles) normally. Whenever a leafy plant is injured it starts to release them in high numbers with some of the compounds stimulating the grown of new cells which help the wounds heal quickly. Some compounds will help the plant by acting as an antibiotic or antifungal aid.

More interestingly it can be used as a distress signal by plants to warn other plants of incoming danger giving them time to put up a defense. An example of this is when giraffes eat acacia trees. Giraffes have developed the understanding that if they approach an acacia grove from down-wind then, as they eat the acacia, the distress signal sent will blow away rather than towards the other trees. This allows the giraffes to continue munching their way through the other trees. This distress signal allows the acacia tree to release a chemical into the leaves that make them taste foul to the giraffe.

Geocoris punctipes

Scientists found, in one study, that the saliva of certain caterpillars reacts with the compounds released by coyote tobacco plants to make them attractive to the Geocoris punctipes AKA “big-eyed bugs” that regularly eat the caterpillars.

There may be a high cost to that wonderful smell of freshly cut grass, though. The compounds released are precursors to ozone formation, according to researchers, and can contribute to the formation of photochemical smog in urban areas.

Cockchafers

A large nocturnal flying beetle that is attracted to light and can often be found bumping into windows or street lights.

Life cycle

Known as May bugs, they start to emerge and be seen during the month of May; however, they can actually be found, as adults, from Late April to July. Their adult lifespan is between five and seven weeks. 

The female lays around 80 eggs in the soil using her pygidium which looks like a stinging point on the abdomen, to ‘inject’ eggs into the earth. The cock chafer is totally harmless to humans and carries no sting.The cockchafer larvae then spends between three and four years in the earth in depths of up to 100cm. They then work their way to the surface only in spring, hence the name “May bugs”.

Appearance

Because of their long development time as larvae, cockchafers appear in a cycle of every three or four years; the years vary from region to region. There is a larger cycle of around 30 years on top of that, in which they occur in the tens of thousands. They are found, more commonly, in the south of England, but are widespread in the UK.

The cockchafer has “feather-like” antennae that are splayed, the female has six fingers on the antenna and the male has an extra one making seven. As with many insects, it is thought that, the more complex the antennae the greater their sensitivity in locating breeding partners and food, detecting danger and possibly for navigation.

The word cock chafer derives from the late 17th century use of the word “cock” meaning size or vigour and to the English word “chafer” which simply means beetle. They are known by many colloquial names such as; May bug, doodle bug (mainly due to how loud it is when it flies), mitchamador, billy witch and spang beetle.

So get out and try to hear of see them flying around lampposts or hear external lights.

Caddisflies

Caddisflies

In the Order of Trichoptera the caddisfly, of which there are approximately 7000 species, starts life in freshwater habitats and then emerge as an adult.

Caddisfly eggs

The name Trichoptera, derived from the Greek words “trichos” meaning hair and “ptera” meaning wings, refers to the long, silky hairs that cover most of the body and wings.

Caddisflies are moth-like insects with two pairs of hairy wings that are folded roof-like over the abdomen at rest. Antennae are long and many jointed with a large basal segment. Large compound eyes are present. [efn_note] Encyclopedia Britannica [/efn_note]

Life cycle

Eggs numbering around 800 at a time are laid in jelly that swells on contact with water. After a few days the larvae hatch. Depending on the species of caddisfly they may be herbivorous, carnivorous, or a bit of both (omnivorous). 

In this larval stage the young caddisfly will protect itself in many different ways depending on the species. Some will spin protective silky webs around themselves. Some will use that silk to make a web to catch food and some will use it to attach debris to themselves to form a protective layer and camouflage from potential predators (see attached video).

Adult caddisflies

The larvae are important to the aquatic community by controlling plant growth and animal and plant waste. The adult caddisflies are unable to eat solids so imbibe nectar from plants instead. 

Parasitic wasps are known to seek it’s host underwater and lay eggs inside the protective case of the caddisfly. The egg hatches and the larval wasp devours the caddisfly larvae.

When the adults emerge, they behave much like moths, they are strongly attracted to light and can be found swarming around objects on the river banks or shore line.

Hopefully you get to see some of these amazing insets when you go pond dipping or moth trapping.
