Why are there so many caterpillars outside my house?
It might be because there's just a lot of pollen and a lot of fresh new leaves. And so there's more food for them. And when there's a lot more food, the babies all survive. So that could play a role.

Browntail Moth (caterpillar stage) Hickory Tussock (the hairs on many tussock caterpillars can cause an itchy rash) Hickory Tussock.
Why do tussock caterpillars itch?
Tussock caterpillars (Erebidae family / previously Lymantriidae) were very abundant in Maine in 2011 and they were ‘itching’ for attention! One reason for all the attention they receive (during late summer and early fall) is that, unfortunately, the hairs on these caterpillars can cause a very itchy rash. The prickly hairs are a defense mechanism (they are not poisonous or venomous). It is important to note that children are more susceptible to the rash than are adults, and children are also much more likely to be playing with them and handling these showy critters (natural curiosity/fascination/playing outdoors). The rash from some of the members of this group tends to be short-lived, and clears up on its own after two or three hours. For other species, however, such as with the Hickory Tussock (see below), the rash can be much more severe and long-lasting, and a doctor’s visit might be warranted to speed one’s recovery and ease the symptoms / discomfort. The Browntail moth is also a member of the tussock group.

What is a tussock moth?

Why are tussock moths called tussock moths?
Similar species: The caterpillars in several moth groups are called “tussock moths” because they, too, may be hairy with clumps of longer hairs. Several of these are in the tiger and lichen moth subfamily.
What is the new family of tussock moths?
The new family (Erebidae) that the tussock moth subfamily now belongs to joins together several additional moth groups. Many of these (such as the underwing, or catocalid moths) used to be members of the formerly huge family Noctuidae. The noctuid family continues, but minus those groups. Another distinct group, the tiger and lichen moths, are in the same situation as the tussock moths: they also used to be in their own family, but have now been reduced to a subfamily (Arctiinae) in the new family Erebidae. These recent taxonomy revisions are confusing, but they represent a much greater clarity in our understanding of the true relationships among these animal groups.
What caterpillars are in cocoons?
The caterpillars incorporate those hairs into the cocoon for protection. Some examples of species in this subfamily include the white-marked tussock moth ( Orgyia leucostigma ), whose larvae damage orchard trees, and the exotic, invasive gypsy moth ( Lymantria dispar ).
How many hair tufts are there in caterpillars?
The caterpillars tend to be brightly colored with distinctive groups of hair tufts, some short and some long, often with 2 long tufts in the front and 2 or 3 at the hind end. The elongated clumps are sometimes called "pencils.". Some species have hollow, barbed hairs that sting with toxic spines.
Why do caterpillars have stinging hairs?
Stinging hairs are a defense against the caterpillars’ many predators. The bright colors warn predators of the unpalatable nature of the caterpillars. The hairs also probably help insulate the caterpillars from extreme temperatures and help protect them from drying out.

What is a tussock moth?

What are tussock moths' enemies?
Predators: Tussock moth larvae have various natural enemies. Medina and Barbosa (2002) looked at predation of small and large Orgyia leucostigma larvae in a temperate forest and suggested that birds were the major predators of large larvae but most mortality of smaller larvae was probably due to failure to find a suitable host during ballooning dispersal and also possibly to predation by invertebrate predators in the leaf litter. Large ground beetles (Henn et al. 2009) and Polistes paper wasps (Castellanos et al. 2011) have also been reported to attack the larvae up in the trees.

Much of the older literature places the tussock moths in the family Liparidae and more recently in ...
When do Orgyia detrita hatch?
In Florida, the overwintering eggs begin to hatch in late February. After hatching, the young larvae feed on the remaining egg mass and then spin a silk thread that they use to “balloon” for dispersal (Thurston 2002). Because adult females are flightless, ballooning by young larvae is the major mode of dispersal. Ballooning is also important given their propensity for spinning cocoons off their host plants (i.e., on buildings, fences, and other man-made objects).
Why is it so hard to control caterpillars in Florida?
Control of the caterpillars is difficult because by the time they are migrating from the trees, it is too late. In Florida, feeding damage to large trees by Orgyia species does not usually harm the trees. However, they may occasionally be sufficiently numerous to completely defoliate large trees. Also, large numbers of larvae blown onto small landscape trees may result in severe defoliation.
What are the black pencils on the prothorax?
