|Gloucestershire Moth Distribution Maps -- Phone Version|
|Delete last||Clear all|
For more details of the map information (e.g. national scarcity and record verification
ratings), see the main version of the page
which is designed for viewing on a computer screen.
To select a species on this version, choose Common or Scientific name (or Food), then enter at least 3 characters on the keypad to see the number of matches (this is shown in large red numerals at the top right of the page). Enter more characters to reduce the number of matches if appropriate, then select the species from the drop-down list of matches. You can limit the matches to micros or macros rather than both.
After viewing the map for one of the matches you can select another match, and you can re-select any of the last 10 selections from the Recent list. The species density map is always available at the bottom of this list.
An alternative way to select a species map is to choose the Species list option. The keypad is replaced by a scrollable list of species names. The position in the list can be changed by small fixed amounts as indicated, or by tapping anywhere on the 'snake' bar (on a computer the position on this can be set by clicking and also by dragging). The coloured background along the snake changes to show some of the family boundaries in the list and there are tick marks at the start of each family.
Tapping anywhere on, above or below the snake's solid horizontal bar sections selects a position on a horizontal section. Tapping anywhere outside this area selects a position on a vertical section. Only positions on the solid sections of the snake correspond to species in the list. Touching the snake area on a phone screen to scroll or zoom the display does not set the snake value on the Android phone used to test this feature.
Tap on any of the species in the list to select its map. The top entry in the list is also shown below the snake in a larger font, with scientific name only for micros and common name only for macros. Tapping on this entry will also select its map.
The sounds checkbox controls the beep on most touch-screen input (there is no beep when the snake value is set).
You can choose 4 types of species display:
-- tetrad (2Km) scale distribution map
-- 10Km scale distribution map
-- tetrad map of number of years recorded since 1990
-- chart showing times of year recorded and numbers of records since 1990
The year period covered by the 2Km or 10Km distribution map is selectable.
Tapping on a 10Km square in the recording area of a 2Km or 10Km map displays the 1Km distribution for that 10Km square, for species recorded from at least 25 tetrads since 2000.
<2, <1, 1>, 2> changes position in the species list by the indicated amount.
Top moves to the top of the page.
The box below the map/chart shows typical larval food(s) in the UK, and species verification comments (if any).
The data used for the species maps is as shown on the main Gloucestershire Moth Distribution Maps page, including VC34 records supplied to the Bristol Regional Environmental Records Centre (BRERC) to the year shown on the maps page, with some from NBN Atlas occurrence downloads at NBN Atlas accessed on Sat Apr 02 07:22:35, 07:28:03 & 07:29:04 UTC 2022, under the Creative Commons with attribution non-commercial licence (CC-BY-NC)
