Carrion beetle.

A carrion beetle - Nicrophorus
You have to admire beetles.  There are over a million species; they are so successful because of their design.  The larvae, called grubs, generally live burrowed into some substrate or remain hidden beneath overburden.  Some are surface dwellers and feed on vegetation.  The adults are really impressive though.  Their first pair of wings has been adapted into a hard chitinous pair of wing covers called elytra.  The whole body is well protected in the same material making them very durable given their size.

Beetles inhabit a tremendous range of niches and display some of the most peculiar behaviours anywhere in the animal kingdom.  Many of them are also quite beautiful, although I fully admit that beauty truly lies in the eye of the beholder.  One of the prettiest beetles I have ever come across is the carrion beetle.

Carrion beetles, both larvae and adults, feed on the flesh of decomposing organisms.  They seek out some dead thing, often a small vertebrate like a mouse, and go about the business of burying it.  This represents no small effort given the difference in size.  Males that are successful in finding a carcass will attract a mate, copulate, then work together to cover up their find.  Eggs are laid and the young and adults both feed on the corpse.  What is unusual is that both adults tend the eggs and larvae. 

I have found two of these over my time hiking about in the woods.  I collected one a couple of years ago and photographed it (above), and this summer I found another.  Both had a number of mites on them, the first had only three but the second must have had over twenty.  Perhaps there is a relationship between their food of choice and being parasitized by these tiny arachnids. 

I used the following website for some of my information:  https://www.fws.gov/midwest/endangered/insects/ambb/abb_fact.html

The maze of life.

The skeletonizing of a leaf by a leaf miner. Born to tunnel; a simple egg laid on a leaf produces a tiny caterpillar.  It immediately becomes an industrial machine, boring into the leaf and consuming the matter between layers.  Barely visible to the human eye, it proceeds in a relatively straight line until it finds an obstacle.  Undeterred, it changes direction and continues its momentum; becoming larger with each centimeter consumed.  The tunnels become larger and its progress faster.  Soon it has consumed almost half an entire leaf.  Thwarted by the main vein running through the middle, it is now large enough to chew through the tougher structure.  Continuing the destruction, the caterpillar finds an outside edge.  It is time to rest.  Spinning silken web, it makes a bed out of the very vegetation it has been consuming.  When it wakes, it will no longer be a caterpillar, but a newly emerged moth bent on laying its own eggs to start the cycle all over again. This caterpillar is

Willow sawfly larvae; not a caterpillar.

Willow sawfly larvae feeding on a willow leaf. Insects can be very hard to identify, and sometimes even getting the right group of insects can be challenging.  The above photo of a sawfly larva is a good example. Initially, one would probably mistake these caterpillar-like creatures as being either butterfly or moth larvae.  Both sawflies and lepidoptera (the group butterflies and moths belong to) have similar looking young.  The easiest way to tell if it is a caterpillar or sawfly is by paying attention to the prolegs. Prolegs are those peculiar suction cup type feet that exist at the back end of caterpillars.  We know all insects have 6 legs, so why do caterpillars seem to have so many more?  It turns out the first three pairs are the true legs.  The caterpillar's head is close to them.  The rest of the caterpillar has a series of false legs, called prolegs, which continue to the end of the individual.  The number of proleg pairs will help identify if it is a sawfly larva

Cottonwood leaf beetles.

Cottonwood is a kind of tree which is usually found around fresh water.  It grows fast and the trees themselves can become very large.  They only live a short time (for a tree) though, around 80 years, and leave their remains as fodder for all kinds of creatures.  The trees are important because of the stabilizing properties they have for banks and beaches.  While alive, the trees are a favourite food of beavers (the bark) and the leaves are consumed by numerous mammal and insect species.  One of those is the cottonwood beetle. Cottonwood beetles reproduce rapidly and can spawn several generations in a season.  Although cottonwood is their primary food source, they will also take poplar, willow, and aspen.  In large numbers, these insects can defoliate a tree and are serious pests in management areas.  As summer ends adults will find their way under bark or leaf litter on the ground.  Those that survive predation and the sc
