514 SEASONS OF INSECTS. | 
Then also the Carabi, like beasts of prey, leave their dark 
retreats,—in this, differing from the Czcindele, which are 
diurnal,—and prowl about to entrap other unwary in- 
sects. Then, likewise, the female glowworm hangs out 
her lamp of love, and the male, led by it, wings his way 
to her: and then the water beetles (Dytisci, Gyrini, &c.) 
forsake the waves and become tenants of the air. 
Could we with certainty discover the stations in which 
insects after their excursions take their repose, we might 
capture many that we now search for in vain. Several 
of these stations were pointed out in a former part of this 
letter where I detailed their usual haunts. I may here 
add, that numbers of them, when reposing, conceal them- 
selves from their enemies on the under side of the leaves 
of trees and plants. Moths, especially the Noctuidae, may 
often be met with in woods, as before observed?, on the 
north side of the trunks of trees. Mr. Marsham related 
to me, that once a little before sunset, observing over his 
head a number of insects on the wing moving on in one 
direction, he caught some of them, and they proved to be 
Forficula minor Li. Struck with the circumstance, he 
watched them several evenings; and on one, as he was 
looking about a melon-pit for insects, he saw these little 
animals alight on the frame, hastily fold up their wings, 
and entering under the glasses, run down its sides and 
bury themselves in the loose earth. This he observed 
repeatedly. ‘The onward flight of these insects was there- 
fore evidently their return from their diurnal cruise to 
their nocturnal station.—This happened in September.
