An indispensable guide to identification, ecology and study of
bumblebees. This new edition embraces the wealth of information
published on bumblebee life history, ecology, foraging, parasites
and conservation in recent years. It includes a new chapter on the
very real threats to bumblebees; their crucial role as pollinators
of our native flora and crops; ways to promote their survival;
advantages and problems posed by their commercial use; as well as
updated colour plates, keys and distribution maps of all British
species (including Bombus hypnorum). The book introduces techniques
and approaches to original work so that anyone with an interest can
usefully contribute to furthering our understanding and
appreciation of these wonderful and important insects.

This Naturalists' Handbook aims to attract more people to the study
of solitary wasps by describing the ecology, distribution and
natural history of these insects, including all relevant research
in one convenient volume. Contents include an overview of the
natural history of the solitary wasp, guidelines on identification,
and advice on techniques and approaches to study. Further reading,
a systematic checklist of genera and an alphabetical checklist of
species and their distributions are included. Detailed keys to the
identification of the species form the centre of the book and the
text is accompanied by clear illustrations throughout, making this
an invaluable practical guide for anyone seeking to broaden their
knowledge of these fascinating, diverse creatures. Smaller, gentler
and less intimidating than the black and yellow social wasps, the
solitary wasps are attractive because of their bright colours and
their fascinating behaviour. A female wasp will construct a nest,
excavating it from wood or sand or building it from mud. She
provisions the nest with prey, hunting down a suitable creature,
perhaps a caterpillar or a fly, which she will paralyse before
dragging it home to the nest. She lays her egg on the paralysed
prey, and the larva when it hatches feeds on the prey. On a sunny
day it is easy to observe the apparently purposeful behaviour of
female wasps as they prepare their nests and stock them with food
for the next generation. This book is a digital reprint of ISBN
0-85546-295-7 (1995). Naturalists' Handbooks encourage and enable
those interested in natural history to undertake field study, make
accurate identifications and to make original contributions to
research.
An introduction to the community of insects that make their home on
thistles. It describes the natural history of the important groups
of insects, and shows how to find them and how to observe their
lives. It also discusses the effects of herbivorous insects on the
plant.
