If I were a Mocking bird, a California Thrasher etc. this would make my day! If I owned a Box turtle, which I do, it would also make My day! What you see are two totally opposing creatures as far as most gardeners would be concerned. One is a thoroughly noxious pest to any sod forming plants such as grasses and other ground covers. The other is actually as beneficial or perhaps more so in the short run than the lowly earthworm!
What you see in this picture are the mature sizes of two beetle larvae. The smallest and more delicate is by far the most destructive to living plants from below the soil surface...especially those plants actively producing a dense network of roots like sod forming grasses and similar plants with a multitude of fibrous roots. The largest mature grub is the larvae of the incredible Fig Beetle! Scary to most people especially if you have had a glass of wine...this irridescent green beetle of rather large proportions will buzz around your head...simply because they are attracted to the scent of ripe or fermenting fruit! Yes, they are quite large beetles and quite imposing especially to those familiar with Bumble bees. They create a deep buzzing sound that is proportionate to their large size.
Once understood...they are quite humorous creatures in flight! They are rather clumsy and slow in comparison to a bumblebee. If you have eaten a couple of ripe peaches, had a beer or a glass of wine they are fun to play with for a game of hide and seek! I know this statement will bring some of you to tears struggling with the idea that any supposedly sane adult might play hide-and-seek with a Fig beetle!!! Believe me it does not take several beers or glasses or wine or taking a peach facial. Therefor enebriation has little to do with it or obsession with soft skin.
To begin fig beetle hide-and-seek one must have a sensitive little finger that is kept moist and held sufficiently away from the body, preferably upwards; and sufficient fruity smells on your hands, face and in your gullet so that you exude "fruitiness". The key factor is determining whether you are upwind or downwind of your beetle playmate. A very windy day will not work as the fruity smells will be too quickly dissipated. So on a warm sunny day with a slight wind... the secret is to get upwind of the beetle if you want it to come towards you...or move downwind to "hide". Once the beetle has gotten close you are doomed to no longer remain "hidden" unless you can run really fast and circle upwind of the flying Fig beetle! Now doesn't that sound like a lot of fun?!
If there are the right number of beetles and the right number of fruit salad eaters, beer, or wine drinkers I imagine everyone would probably be bumping into each other and the beetles might appear to be swarming...or at least quite confused! Gee! I can almost hear "A Midsummer's Night Dream"! Such frollicking chaos of lovers and things in the night! (Only, in broad daylight!)
OK! I am sure you get it ad-nauseum!
But really...there is no need to be squeamish about fig beetles!
Mice...well, a mouse is in the house I might quite agree!
I know that for most an "insider spider" gives you the chills...
but I would rather have an insider-spider... than a roach on my toast!
Don't forget that some insider-spiders keep you from having ants in your pants!
I have been well assured you will never find a grub in your tub!
Unless someone was pretending that they didn't like you!
So now you can join the Grub Club and be free of all kinds of freaking stuff!!!
Now what makes a beetle a Fig beetle? Since they are primarily from a mediteranian climate where figs grow they have commonly been associated with figs as they ripen and ferment on or below the trees before they are harvested. Thus this exotic large beetle and the even larger grub which is a boon to all gardeners in a meditteranean type clime is commonly named the Fig Beetle. Adults enjoy with incredible gusto almost any fermenting or over-ripe fruits to the point of utter distraction! Fruit on the ground or in a tree can be picked with one or more beetles intact, very much unwilling to release their position...I wouldn't be afraid either if I were equiped with such tough coverings all round my body, possessing spiny legs with enough strength to loosen myself from all but the most ambitious predator or human hand!
The very well fed fig beetle's next destination is to find the scents of rotting plant materials found in your compost pile of kitchen garbage and gardening prunings. AND what do you have but a critter that is at least in the short term, much more effective that the lowly EARTHWORM. You shall see pics displaying poop from this bulbous critter that is not any different from earthworm poop! It has a similar earthy smell as earthworms far from the rotting things that it ingested. As with earthworms this insect works in conjunction with beneficial bacteria and other organisms. I would not normally find a grub in a smelly, stinky mass of rotting plant material any more than I would find earthworms there. There is probably a specific chemistry and things like a balance of O2 and CO2 and pH. The right kinds of bacteria and fungi are probably as important as the nutrients of the plant material that is available.
Just look at that nutrient rich NON-smelly poop...on my finger on the fabric and in process of excretion! It is black and has a very similar water content as worm poop. When left alone in drier conditions they make discreet little pellets that are great for sprinkling on your potted plants!
I open a challenge to anyone who can prove to me that the poop from the Fig Beetle larvae is any less potent than earthworm poop! They also have a superior ability to turn many more, and tougher plant materials into this wonderful poop. Banana peels, melon rinds, and the stemmy parts of vegetables that we don't like to eat seem to almost disappear into a dark mass of nutritious microbially active compost! The only other insect that goes perhaps one step furthur in conversion of waste materials is the Black fly. See some of my earlier blogs for pics and info. Having even more of a limited season than the Fig beetle or the earthworm they also have a disproportionate appetite for many plant AND animal materials. They are another must have critter in terms of clean composting and recycling of garbage!
Now that you have been introduced to this pretty big grub and the fact that it becomes this big beetle that may buzz around your head at a Saturday afternoon party what do you want to live with? Choice #1, the May/June bug which you see only at night around bright lights and in dead patches of lawn turf and faltering garden plants. Choice #2 The Fig Beetle which you see only at your extravagant garden parties and when you turn over your compost pile!
This small grub (notice my fingers) has a pair of small sharp mandibles (projections that are surrounding or outside of the actual mouth) capable of tearing into the toughest of roots or taking small pieces of root that can be ingested in smaller pieces by the mouth.
The difference in the larger of the two grubs, the Fig beetle larvae is obvious in that the "manidible" is meant for mashing as opposed to cutting or tearing. I submit that both grubs especially the Fig beetle are quite strong of "jaw" or mandible. However the fig beetle holds the record for mobility even amongst catepillars by "back lapping" rather than dealing with a bunch of pseudo-legs ...there is no more obvious contendor to grub or catepillar racing than the Fig beetle grub. I have seen Wooly bear catepillars do a pretty good sprint! The June/May beetle struggles when exposed upon hard or compacted surfaces where the Fig Beetle flips on its back and is off in a flash! Meanwhile the June/May beetle larvae dies where it has been exposed! (If it hasn't been picked off by a Mocking bird or other thrush bird like the Robin.
If you are a naturalist at heart you would ask why the larger of the two grubs is the most agile? Well the smaller grub is used to living in a more or less moist, confined environment where there are an abundance of living roots. It's ultimate daily effort is moving a few inches through the soil eating roots. The larger grub is in a shallow level of soil most of the time where there are continual layering of decomposing plants. This grub is not dependant upon root systems but upon the availability of varying degrees of decomposing plant materials that requires a greater mobility to find the most desirable material. If I was a big grub with perhaps a great variety of nutrient requirements I certainly would opt for greater mobility. I would also be capable or creating small burrows into which I could withdraw quickly to escape a skunk or an opposum or in some circumstances a ring-necked snake or an alligator lizard.
Now you will hear my RANT! It is quite unfortunate that the USDA insists upon lumping the Fig beetle in with it's close relative the May/June beetle. Most of the genus to which they belong are pests when it comes to the root systems of living plants. I have spoken to those who are members of the above and have written documentation from this agency. It is all BS because there is no evidence that they can provide except for the generalities of the activities of the genus of beetle in question. I will claim to my grave that the Fig Beetle is totally benign when it come to our efforts to garden and produce material which will allow us to survive. What if someone blamed you for certain activities just because you looked like someone who supposedly displayed those activities? Choose your grub! I want to get a real vote on this! I dare you! It all comes down to soft and succulant or big and tough. Just remember that terms and definitiions relative to whom we are, are always relative!
