please let me know!). To the best of the knowledge of the contributors all
the images have been identified correctly. However with such a wide variety
of shapes, forms and many similar species there is always scope for error - so accuracy cannot be
The sizes quoted for larvae are approximate because they are
so difficult to measure and their length varies with the way they are resting.
These measurements have been included, where available, so that the appearence
of larvae found in the field can be compared with those of about the same
size. Technical terms have been avoided as far as possible to make the site
easy to read for all ages and experiences and larva has been used in preference
to caterpillar to save space! The timescales quoted for larval stages are
approximately the time between the first young caterpillars appearing from
the earliest eggs laid to the fully grown caterpillars from the last eggs
to be laid. The time periods and appearance of all these activities are obviously
quite variable depending on weather conditions throughout the year.
Thousands of photographs are needed for this
ambitious project, the aim being to illustrate each species with images
of (A) The egg, (B) Young and final instar larvae - with pictures of intermediate
stages where there are significant changes in the appearance, shape or markings
of the larvae - also different colour forms, (C) The cocoon (if one is 'spun' above ground), (D)
Examples of male and female pupae and (E) Examples of the adults.
A separate section of the website contains close up photographs
of various parts of a selection of pupae to aid species identification.
If you can help by providing photographs to fill
in the gaps in stages or colour forms of those species already illustrated
or any early stage of those species not listed so far, please contact Reg Fry by
clicking on this
e-mail address. PLEASE do not use this e-mail address for identification
queries as I am unable to respond to them individually. Many of the caterpillars frequently seen in the UK are illustrated
on the Life Cycle page of this website so have a look through this first and if this does not help
try one of the Lepidoptera forums such as that listed on the home page.
In the species lists I have added a ^ symbol to those species for which I can only find photographs of the adult.
What is the best way to help? I am able to
scan in positive or negative film or prints so the loan of these would be
very useful. Digital files are obviously the easiest way of sending photographs
as e-mail attachments. If you have broadband I would prefer to receive jpeg
files of the original photographs of any size up to say 3MB. This allows me the
best scope to adapt the image to fit the website and show the insect off
to the best advantage with others of the same species - if you want to work
on the photographs yourself the frame size of images on the website is 740 pixels wide and final instar larvae are generally 450 pixels high.
Don't worry if parts of a photograph are a bit out of focus or need other improvements
- very few (if any) photographs of insects are perfect - I have had to improve
every one of my own in one way or another!
Finally, if you have surplus livestock of any species that I could rear and photograph for the website,
that would also be much appreciated.
