Invertebrates are animals with no backbone. Large species groups such as insects, spiders, molluscs, worms and crabs are invertebrates. They represent over 90% of all living animal species.
Contrast that figure with the fact that vertebrates (animals with a backbone like humans) comprise only 5% of the total animal species.
We focus most of our interest and scientific research effort on vertebrates, even though the food chain relies so much on invertebrates. Invertebrates not only provide food for birds and humans but also have a critical role to play in plant pollination. Bees are important pollinators but they are alone in fulfilling that role.
We do not consider insects to be important, if we did we wouldn't wipe them out as indiscriminately as we do. We spray crops and weeds with insecticide, cut down undergrowth, mow grass verges, we keep the countryside looking neat and tidy when we should be leaving grass long and wild flowers uncut, as these are the type of habitat that support insects.
A simple exercise will show how insect numbers have tumbled in recent years. Remember when you got back from a longish journey in a car - how the front of the car was covered in dead insects? The windscreen used to be splattered with them. Check out how many dead insects there are on the front of your car these days. Hardly any.
Without insects food chains will collapse, and we are doing nothing to halt the decline in habitat loss. Why not leave a wild area in your garden, hassle the council to leave grass verges uncut (as long this doesn't affect road safety), tell your friends to do the same.
Rant over - what about the insects seen in and around Hornsea recently?
Hoverflies are my current favourites:

| Long-winged Duskyface (Melanostoma scalare) |

| Lanuled Aphideater (Eupeodes luniger) |

| Ringed Beech Fly (Fagisyrphus cinctus) |

| Tiger Marsh Fly (Helophilus pendulus) |
 |
| Yellow Bowed Smoothwing (Scaeva selentica) |
There are a few more but I'll leave hoverflies there. I've found 29 species so far in and around Hornsea but I've only scratched the surface!
Butterflies will hopefully be more numerous this year after last year's disaster. Eight species so far for me and a few have been seen recently:

| Green-veined White |

| Large White |

| Peacock |
Moths have been very scarce so far, with just a single species seen during the day.

| Large Yellow Underwing |

Beetles - again I haven't seen many beetles yet this year, but no doubt they will appear eventually. This one was a new one for me, a soldier beetle species:
%20insect%20book%20absent%20%20(4).JPG) |
| Soldier Beetle sp. (Cantharis pellucida) |
Flies aren't exactly good subjects for photos but Scorpion Flies are quite pretty!
 |
| Scorpion fly - Panorpa germanica |
Bees - so many to choose from and despite news to the contrary, they are out in good numbers as far as I can see.
 |
| Common Carder Bee |
 |
| Mining Bee sp. possibly Chocolate Mining Bee |
The above are just a small sample of the wide range of insects that are all around us, going on about their business and causing us little or no problems. I have come to enjoy looking for them through the summer months as they add a different perspective to wildlife watching. More to follow in the forthcoming posts (I hope!).
