(LINNAEUS, 1758)
The Drinker caterpillar lives in tall, mainly damp grassland and
is named for its habit of drinking drops of dew or rainwater.
The whitish, gray-marked eggs are laid in small groups
attached to grass stems. The caterpillar, while small, hibernates
near the ground in dense grasses and feeds, mainly at night,
the following spring. It is often seen resting on grasses by day,
and contact should be avoided as the hairs can cause skin rashes.
The caterpillar pupates in a yellowish, papery, tapered cocoon
low down among grass stems.
The large, furry, chestnut-brown or orange-brown adults y
from June to August in a single brood. The Lasiocampidae
(often known as eggars and lappets) are medium-sized to large
moths found in most parts of the world. The caterpillars all have
a dense covering of short hairs and tufts of longer hairs. Many
are conspicuous by day but, due to the hairs, are not eaten by
most birds, except cuckoos.
The Drinker caterpillar is dark gray and
intricately patterned, with a distinctive long,
Actual size slender, black or brown hair tuft near the front
and back end, irregular yellow lines along the
back and sides, and white and rusty hair tufts
along the lower sides. It also has extensive short,
rusty, and black hair tufts and longer, pale hairs.
